UD Trucks Corporation (UD, UD Torakkusu Kabushikigaisha) is a Japanese firm that specializes in the production and distribution of diesel trucks, buses, bus chassis, and special-purpose vehicles. The company’s headquarters are in Ageo, Saitama, Japan. Since 2021, the company has been a completely owned subsidiary of Isuzu Motors. Nissan Diesel was the company’s name until 2010.
The UD moniker was first used to the company’s Uniflow Diesel Engine (a two-stroke diesel engine), which was introduced in 1955, but is now promoted as “Ultimate Dependability.”
Who makes the diesel engine for Nissan Titan?
The 2015 North American International Auto Show saw the launch of the 2016 Nissan Titan XD full-size pickup, which is powered by a Cummins 5.0L V8 engine.
Cummins’ footprint in the North American pickup industry has expanded beyond heavy-duty trucks to now include light-duty pickups with the next-generation Nissan Titan. Between the lesser and larger diesel alternatives in the pickup market, the 5.0L V8 Turbo Diesel stands out.
Since their relationship began in 2007, Nissan and Cummins have collaborated on optimizing a calibration and unique hardware for the Cummins 5.0L V8 Turbo Diesel. Since then, the engine has undergone extensive testing, including numerous hot and cold test cell hours and over a million tough test miles, in order to prepare it for production later in 2015.
The 5.0L V8 Turbo Diesel combines a compacted graphite iron (CGI) cylinder block with a forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers to provide optimal durability in a lightweight package. These elements, together with twin overhead camshafts, contribute to the 5.0L V8 turbo diesel’s excellent noise, vibration, and harshness (NVH) characteristics.
The Cummins M2TM Two-Stage Turbocharger is designed to operate efficiently at both low and high engine speeds. The latest Bosch High Pressure Common Rail (HPCR) fuel system and piezo fuel injectors deliver precise fuel control for enhanced in-cylinder combustion, resulting in improved fuel efficiency and lower emissions. The HPCR fuel system, in conjunction with the Cummins M2TM Two-Stage Turbocharger, provides to a very high peak torque of 555 lb-ft and 310 horsepower, thanks to multiple injection events controlled by integrated electronic controls.
The innovative ceramic glow plug technology minimizes start time and electrical current draw in cold conditions, lowering vehicle charging system requirements. The ceramic glow plugs are made to last the entire life of the engine and require no maintenance.
The latest NanoNetTM media from Cummins Filtration is used in a two-stage fuel filter system for the 5.0L V8 Turbo Diesel to ensure that the HPCR fuel system is fully protected against fuel contamination. NanoNet’s innovative design allows for higher fuel flow and catches more than 99 percent of all particles as small as 4 microns.
Cummins’ considerable emissions technology experience is used to create proven air handling and emissions control solutions. Cummins M2TM Two-Stage Turbocharger, cooled Exhaust Gas Recirculation (EGR), and Cummins Emission Solutions Aftertreatment System, which includes a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), produce near-zero NOx and PM emissions while improving performance and fuel economy.
Is Nissan still using Cummins engines?
After four years of manufacture, the Nissan Titan XD Cummins is no longer available. The Cummins turbodiesel 5.0-liter V-8 will be phased out of Nissan’s full-size truck starting in 2020. It’s all part of a plan to stop the brand from bleeding. Nissan recorded a 44.6 percent reduction in operational profit from 2017 to 2018, while Titan sales were down nearly a quarter from the same period last year, at little more than 18,000 units in the first half of 2019. Ford sold approximately 450,000 F-Series cars during the same time period.
Is the Nissan Titan Cummins good?
Overall, the 5.0 Cummins engine in the Titan XD has a lot of problems. While the engine’s key components, such as the heads, block, and internals, appear to be sturdy and keep up well, the rest of the engine does not. The block and major engine components were all made by Cummins, which is probably why they don’t have any severe problems. Nissan is in charge of the engineering for all of the major engine systems on these trucks that are causing problems.
The Titan XD’s emissions systems are all troublesome; turbochargers are known to fail prematurely, the fueling system has flaws, the transmission is terrible, and so on. Aside from these fundamental engine issues, the XD was already lacking. The engine was about $10,000 more expensive than the V8 gasser predecessor, yet it only increased towing capacity by 1,000 pounds. Furthermore, the ride quality, interior, and overall driving experience were much inferior to that of its Dodge, GM, and Ford competitors.
While we believe the 5.0 Cummins engine is a very durable and strong engine, we do not believe the 5.0 in the Titan XD is trustworthy. We believe the block, heads, internals, and other components will last up to 300,000 kilometers. We simply do not believe that a Titan XD with the 5.0 Cummins engine will achieve that level of mileage without tens of thousands of dollars in maintenance and repairs along the way.
Another compelling reason to avoid these engines is that they are no longer supported by Nissan. Since this engine has been phased out and no other diesel trucks are available, all diesel truck mechanics at dealerships have been laid off.
Is a Duramax better than a Cummins?
Torque is the most important factor in hauling, but horsepower isn’t far behind. Whether you’re towing or not, more horsepower means faster acceleration. With 445 horsepower, the latest Duramax 6.6L L5P diesel dominates this category. The modern Ram Cummins 6.7L 24V diesel engines have 400 horsepower. Historically, the Duramax line has had a modest horsepower advantage over the Cummins line.
Why did Nissan stop making diesel trucks?
Due to low sales, Nissan is retiring its diesel-powered Titan XD truck. According to a letter delivered to U.S. dealers last week, Nissan will stop producing the diesel-powered Titan XD pickup after the 2019 model year and replace it with a gasoline-powered equivalent.
What kind of diesel engine does Nissan have?
The 5.0L Cummins’ outstanding performance statistics are mostly due to the engine’s superior turbocharging and fuel injection systems. These trucks have 310 horsepower and 555 lb-ft of torque out of the box. The maximum towing capacity is roughly 12,314 pounds. Advanced emissions controls enable this engine to be as clean as it is powerful. All of this power is channeled through a 6-speed heavy-duty Aisin transmission.
We’ll go over all of these distinct performance qualities and how they work in greater depth below.
L Cummins V8 Turbocharger System
A unique, extremely advanced dual sequential turbocharger technology is used in the Nissan Titan XD Diesel truck. This new M2 turbocharger setup, which is made up of two distinct turbochargers, is supplied by Holset (Cummins Turbo Technologies). This design delivers outstanding performance across the whole power spectrum. A smaller turbocharger offers faster throttle response and acceleration, as well as appropriate performance in low-airflow situations. At higher engine speeds or under heavy loads, the bigger turbocharger gives superior performance.
The air flow between the two turbos is controlled by an unique rotary valve. It opens ports so that a bypass or wastegate function can be performed. It also manages the temperature of the exhaust following treatment.
Cummins 5.0ISV Fuel System
Bosch’s High Pressure Common Rail (HPCR) is used in the Cummins 5.0ISV. A Bosch CP4.2 injection pump, capable of pressurizing fuel to 29,000 psi, is at the heart of this system. The fuel injectors used are piezo fuel injectors, which may fire up to 7 times each combustion event. Before the 5.0L Cummins, piezo injectors were recognized to provide quiet operation and had benefited other diesel trucks.
While modern diesels’ new fuel injection systems are quite powerful and efficient, the Bosch CP4.2 has been known to be extremely sensitive to poor fuel quality. An innovative Cummins two-stage fuel filtration system is used to assist protect the entire fuel system. It uses Cummins Filtration’s newest NanoNet media to deliver much better fuel filtration. The NanoNet filter media improves fuel flow while catching 99 percent of all particles as small as 4 microns.
While emissions devices have little impact on the performance of the Nissan Titan XD 5.0L Cummins engine, they do make it exceedingly clean. Exhaust gas recirculation, Selective Catalyst Reduction, and a diesel particulate filter are all features of the Cummins 5.0ISV engine. These devices emit nearly no nitrogen oxides and just a small amount of particulate matter.
Ceramic Glow Plugs
Ceramic glow plugs are used in the 5.0L Cummins Engine for greater cold weather performance. They make it easier to start the engine in extremely cold temperatures and cut start-up times in half. They also reduce electrical current draw, lowering the demands on vehicle charging systems. These ceramic glow plugs are designed to last the lifespan of these cars and should not require any maintenance.
Because the Nissan Titan XD is equipped with a 5.0L Cummins Diesel engine, it is quite easy to boost performance. Diesel trucks are extremely adaptable and frequently have a lot of untapped potential. A few of the greatest Nissan Titan XD 5.0L Cummins Performance Upgrades are listed here.
Does Nissan offer a diesel truck?
The Nissan Titan XD is still available. The diesel alternative, on the other hand, was phased out in 2019. Think twice before buying a secondhand Nissan Titan XD with the famous Cummins diesel engine. It was such a disappointment that diesel engines are no longer available in current versions.
The 2019 Nissan Titan XD is available for around $32k new, and used vehicles can be found for a similar price depending on where you live. The 2019 Nissan Titan XD Diesel, on the other hand, costs around $42,000.
However, production of the 2019 Nissan Titan XD with Cummins diesel was halted in order to prepare for a big update of the Nissan Titan in 2020. The Nissan Titan XD Diesel was likewise phased out due to poor sales.
What is wrong with the Nissan Titan?
There are numerous transmission issues with the 2016 Nissan Titan. Many owners have reported their trucks jerking and lurching while shifting, while others have stated that their transmission jerks sporadically while shifting. Some drivers have also complained about their trucks abruptly stopping while traveling.
Finally, some Titan owners have complained that their transmission has fractured over time, causing damage to the drivetrain. There have been no recalls or known remedies for these types of transmission difficulties as of this writing.
