Can You Put A Diesel Turbo On A Gas Engine?

To begin, you should be aware that if you drive carefully, both turbochargers and diesel engines can be more efficient than regular gasoline engines. Turbochargers boost the horsepower of your gasoline-powered engine. They accomplish this by boosting the amount of air and fuel that each combustion chamber receives. Diesel fuel, on the other hand, burns at a lower temperature. This results in more exhaust gas being produced, although diesel engines also have higher compression ratings. Because a diesel engine burns less fuel, you’ll see a boost in your fuel efficiency if you drive carefully.

Are petrol and diesel turbos the same?

To withstand the high combustion pressures produced by diesel fuel, diesel engines are typically larger and stronger than their petrol counterparts.

However, because of their larger size, diesel engines have a harder time running at higher revs per minute (RPM), which means they have a harder time drawing in enough air to generate more power. If a corporation wishes to increase the power output of a diesel engine, turbochargers come in handy since they make the work of getting more air into the engine much easier.

Another distinction to note is that turbochargers in diesel engines often provide just a modest gain in power, especially when compared to turbochargers in gasoline engines. The installation of a turbocharger on a diesel usually has more to do with dependability and reliability than with increasing power output.

A turbocharger on a petrol engine is more concerned with increasing power. In the end, petrol turbochargers are smaller and built to run at significantly greater RPMs than diesel turbochargers.

Because turbochargers in petrol engines must operate at significantly higher RPM bands, they must be able to accelerate more quickly than their diesel equivalents. Turbo petrol engines generate more heat than diesel engines because they must run at higher revs, necessitating the usage of a cooling system.

Can you put a turbo on a gas motor?

The sixth step is to find a turbocharger. On paper, you may construct a whole system using the math. You can add nearly any turbo to any engine using the science of compressor mapping and a rough notion of the size and rpm range of your engine. The availability of the maps, as well as the A/R ratios of the turbine housing and turbine wheel sizes, are the key. On a V-8, small factory engines produce small turbos with internal wastegates that must be run in pairs. On OE automobiles, they’re also usually water-cooled for longevity. They’re usable, but they’re far from ideal. Take, for example, a Garrett T03 from a T-bird turbo coupe from 1985 to 1986. The basic coupe has an A/R of 0.63 and a compressor efficiency map built for a 2.3L four-cylinder engine, whereas the automatic transmission coupe has a single turbo with an A/R of 0.48. Using the map in the Junkyard Turbo sidebar, it’s easy to drop the turbos down to roughly 65 to 68 percent efficiency with a boost pressure ratio of 1.68 (14.7+10/14.7=1.68). You must increase the boost to the ragged edge of boost safety to optimize efficiency. It will deteriorate with a larger engine. It’s doable; you’ll simply have to be cautious about what you do.

Can you run diesel in a gas engine?

Diesel is classed as a combustible, but gasoline is classified as flammable. That is, a diesel engine cannot run on gasoline, and a gasoline engine cannot run on diesel. Diesel is too thick for the fuel pump system of a gasoline engine, and gasoline produces too much of an explosion for the diesel engine to handle.

What is the advantage of turbo diesel engine?

  • Diesel is 33 percent more fuel efficient than gasoline, and turbochargers improve diesel fuel economy even further.
  • Improved performance: As horsepower is increased, emissions are reduced and altitude compensation is improved. The power output of a turbocharged engine is increased for a given engine weight.
  • More torque is produced as a result of the increased air admitted into the cylinder, which raises air density and pressure, allowing more fuel to be injected, resulting in more torque and thus more power. Torque at low speeds has also been enhanced.
  • Better towing capabilities: Compared to normal diesel and gasoline engines, the engine offers a higher towing capacity. A turbocharged engine is therefore the greatest choice for farm machinery and vehicles that must carry big loads and operate in off-road terrains.
  • Turbocharging allows automakers to lower engine sizes while still delivering power and performance, which is better for the environment. Greenhouse gas emissions are lower with smaller engines.

Does turbo diesel use more fuel?

To begin with, a 1.6 litre turbo engine is physically smaller and lighter than a 3.0 litre non turbo engine with comparable power (naturally aspirated engine). This results in fuel savings due to weight savings and fewer internal engine components, which cause less drag as they move around together.

Understanding how an engine and turbo work is necessary for the second benefit. In simple terms, your engine, whether diesel or gasoline, is an oil burner. It generates power by burning fuel to turn the wheels. Despite numerous technological advancements, this is still a relatively inefficient method of energy production. The energy extracted from your fuel is split as follows: approximately 35% goes to power (productive work), 35% goes to exhaust, and 30% goes to heat (which is transported through coolant and oil). Diesels have a somewhat higher power efficiency, which explains why they can attain better fuel economy.

Turbos are fueled by the energy that would otherwise be squandered as it exits the exhaust pipe. A turbo is made up of two fans that are connected by a shared shaft. The exhaust fan is in the exhaust stream, whereas the intake fan is in the intake. The exhaust turns the fan (known as the turbine), which powers the intake fan (the compressor). Boost pressure is created, allowing additional air to be pumped into the engine. In simple terms, a 1.6 litre engine with 14 psi of boost can now flow as much air and, with proper fueling, make as much power as a 3.2 litre non turbo engine, but with less weight and better efficiency, as previously discussed. Turbo fuel savings can be as high as 8%-10%, but be warned: put your foot down and these small engines will show you just how much power they have, and that they can burn just as much fuel as the big ones when pushed to their limits.

Can diesel engine be turbocharged?

  • Because the torque regulation is based on the mass of fuel injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture, a “lean” air–fuel ratio, generated when the turbocharger pumps excess air into the engine, is not a concern for diesel engines.
  • Turbocharging effectively improves the compression ratio, which can induce pre-ignition and high exhaust gas temperatures in a gasoline engine. Fuel, on the other hand, is not present in the combustion chamber throughout the compression stroke of a diesel engine since it is only introduced soon before the piston reaches top dead center. As a result, there can be no pre-ignition.

An intercooler can be used in turbocharged petrol engines to cool the intake air and hence enhance its density.

Which is better turbo petrol or turbo diesel?

When it comes to German automobiles, we have always liked turbo-diesels. That’s for a variety of reasons. The massive torque is addictive, and diesels are generally more durable and reliable than gasoline engines. Furthermore, unlike a few performance petrols that require high octane fuel, they run on standard diesel quite well, and their greater fuel efficiency (30-100 percent higher) results in a longer highway tank range. Finally, when it comes to selling a high-end car, a diesel variant is often easier to sell than a petrol version. That’s because to the FE-obsession that is ingrained in every Indian’s DNA.

However, things have changed since then. Audi, BMW, and Mercedes-Benz all have wonderful, thrilling turbo-petrol engines (related thread). Natural-aspiration gasolines have all but vanished from luxury vehicles.

Let’s look at the BMW 530i and 530d models. The 530i is equipped with a 2.0L, 4-cylinder turbo-petrol engine that produces 249 BHP and 350 Nm. It can sprint from 0 to 100 km/h in 6.1 seconds. The 530d, on the other hand, is equipped with a 3.0L, 6-cylinder turbo-diesel engine that produces 262 BHP and 620 Nm. It can accelerate from 0 to 100 km/h in under 5.7 seconds. For the turbo-diesel, this appears to be a cakewalk. The gasoline, on the other hand, is not slow by any means, and when you consider the price, it becomes an appealing option. The 530i M-Sport costs Rs. 60.90 lakhs, cheaper than the 530d M-Sport by Rs. 7.50 lakhs. If you choose for the 530i Sport, which costs Rs. 55.40 lakhs (6-cylinder diesel isn’t available in the lower variant), you’ll save a lot of money.

The 330i and 320d, both from BMW, are at the bottom of the lineup. The 2.0L 4-cylinder turbo-petrol engine in the 330i produces 254 BHP and 400 Nm. It can accelerate from 0 to 100 km/h in just 5.8 seconds. The 320d is powered by a 2.0L turbo-diesel engine with 400 Nm of torque and 187 BHP. It has a sprint time of 6.8 seconds from 0 to 100 km/h. As a result, the turbo-petrol is faster than the diesel! It’s much more appealing because of the pricing. The 330i Sport is Rs. 50,000 less expensive than the 320d Sport at Rs. 42.90 lakhs. Only the 330i M-Sport is Rs. 1 lakh more expensive than the 320d Luxury Line, at Rs. 49.30 lakhs.

Mercedes-Benz has two models available: the C200 and the C200d. Both vehicles use 2.0L 4-cylinder engines. The C200’s gasoline engine produces 200 BHP, while the diesel engine produces 191 BHP. The diesel is 0.8 seconds faster than the petrol at 0-100 km/h, clocking in at 6.9 seconds. The petrol costs Rs. 41.31 lakhs ex-showroom, which is nearly Rs. 2 lakhs less than the turbo-diesel, which costs Rs. 43.38 lakhs.

If you enjoy Audis, your options are limited because the brand now only sells turbo-petrols. The VW Group has yet to make its diesel vehicles BS6 compliant.

Compared to the diesel engine, the turbo-petrol engine provides a number of advantages. To begin with, a turbo-petrol engine revs higher, making it more enjoyable to operate. The pure thrill of revving a diesel engine to 6,500-7,000 rpm is something that only diesel enthusiasts can imagine. The refinement is also much better, with less engine noise and vibrations entering the cabin. Even if the turbo-petrol engine can be heard inside the cabin, it will almost definitely sound better than the diesel. Apart from these considerations, with 10-year-old diesels becoming banned in some parts of the country (Delhi-NCR), turbo-petrol may be the only sensible option for you if you plan to keep your car for a long time, as the majority of BHPians do.

However, as compared to turbo-diesel, the turbo-petrol has some drawbacks. We are prepared to wager that the resale value will be lower because the fuel efficiency is lower than that of the diesel. When traveling outside of major cities, the quality of diesel available at gas stations may be superior to that of gasoline. A diesel is the only alternative for those who desire a 6-cylinder engine.

Who needs diesel turbos?

Baby, you have a lot of power. They are in desperate need of assistance. When diesel engines are naturally aspirated, they aren’t very efficient. They’re dogs, after all. Put the turbo on and you’ve got some serious power. Diesel engines are designed to produce more torque. Under acceleration, the turbo allows the diesel engine to have some get-up-and-go.

The increased horsepower allows the diesel to be used on the road. The diesel would be unsafe to drive on the road without it. It has the potential to be quite hazardous. You’ll need the power to pull out onto the road without causing an accident.

Diesels would have very little horsepower if they didn’t have turbos. They require assistance, and when they work together, they achieve greatness.

Can a turbo damage your engine?

Downsized turbocharged engines have become the new standard to battle fuel efficiency. Smaller engines consume less gasoline, but turbocharging adds pressure, which can cause higher temperatures and engine knock, resulting in engine damage. You must have a lower compression ratio to avoid this. The compression ratio and thermal efficiency are inextricably linked. To lower the temperature, you must pump more fuel into the engine, resulting in a higher fuel to air ratio, and your fuel economy suffers as a result. Because of the high fuel to air proportion required to safeguard the engine, turbocharged engines are inefficient when asked for full power.
