Isuzu Engine Technology

The Isuzu 6H 7.8L Diesel Engine is an engine that incorporates the worldwide knowledge of Isuzu diesel engine technology. The 6H’s excellent performance and quality are based on the many technological advantages the engine has over competing engines.

  • Ladder frame for light weight, high rigidity, low noise, and low vibration
  • Precision machined fit sleeve for serviceability and better durability and reliability
  • OHC, 4 valve layout for performance, low emissions, and good fuel economy
  • Piston with cooling channel, nitrided crankshaft, and axial oil seal for durability and reliability
  • High pressurized fuel injection and damper (viscous-rubber type) for low noise and low vibration.
  • Oil cooler with temperature regulator valve for fast warm-up
  • On the 6H engine, the fuel injection system is a common rail system from Denso Corporation
  • The fuel injection pump, fuel common rail and the fuel injectors are made by Denso

One of the main features in using the common rail system is independent control of fuel injection by the engine computer.

This independent control allows for emission and power optimization in the design process. Noise reduction, knock reduction and overall combustion efficiency also arise from the use of pilot injection.

The 6H pilot injection injects a small amount of fuel just prior to the conventional fuel injection pulse. This pilot injection has been a strong factor in the effectiveness of the 6H in achieving lower NOx emissions and more responsiveness in cold starting conditions.

The pilot injection feature improves engine performance on the 6H in any operating condition. The fuel injection process is further enhanced by the self-diagnosing features found on the closed loop fuel control system.

The common rail system detects engine conditions (engine speed, accelerator pedal angle, coolant temperature, etc.) by means of its sensors and feeds back this data to the fuel injection algorithm calculations

Isuzu 4H 5.2L Diesel Engine is an engine that incorporates the worldwide knowledge of Isuzu diesel engine technology. The 4H’s excellent performance and quality are based on the many technological advantages the engine has over competing engines.

The NPR-Series Gasoline vehicle is powered by the GMPT-V8 gasoline engine. The basic features of the Vortec 6000 V8 are 8 cylinders, 4 stroke operation, and 365 cubic inch displacement.


The LQ4 GMPT Vortec 6000 V8 truck engine has been designed to deliver better performance, high fuel economy, less noise, lower emissions and reduced maintenance than its predecessor.

The Vortec 6000 delivers more horsepower than the competition’s V-10 with the fuel-efficiency of a V-8, and it beats the competition’s gasoline-powered V-8s when it comes to peak torque.

The Vortec 6000 is equipped with a new close-coupled catalytic converter system, which helps to reduce emissions and provide more customer value. The system consists of two 102-cubic-inch (1.7 liters of volume per bank) converters, placed five inches from the exhaust manifold, and a close-coupled Y-pipe.

The converters are bolted (rather than welded) to the exhaust manifold flange. They have a standard construction, consisting of a ceramic substrate, insulating blanket material and a steel shell.

The new architecture replaces two previous mid-coupled converters.
The Vortec 6000 engine meets Federal emissions requirements and California Low Emissions Vehicle (LEV I). It also meets near-zero evaporative emissions standards in all states.

Businesses have discovered that Isuzu medium duty trucks work like a big truck, but handle like a company car.

They like the unsurpassed visibility and maneuverability, ease of maintenance, plus high driver satisfaction and productivity Isuzu trucks deliver year after year. Such trucks are the N series, F and H series. New 2007 Isuzu cars are the SUV’s Ascender 5 and 7 passenger, I-280, I-290, I-370 and the 2006 model I-350. Earlier include the Trooper, Bighorn, Rodeo and a few others.
