2-valve cylinder head

Cross flow head design that provides excellent breathing from a lower cost two-valve cylinder head

High-pressure common-rail (HPCR) and engine control unit (ECU)

The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 1600 bar (23,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of the injection

Fixed geometry turbocharger

Fixed geometry turbochargers are sized for a specific power range and optimized to provide excellent performance across the entire torque curve. They are also designed to maximize fuel economy between the engine's rated speed and peak torque.

Air-to-air aftercooled

This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs

Multiple injection strategy

The new HPCR fuel system and engine control unit (ECU) allow for multiple fuel injections. The number of fuel injections, based on speed and load, help contribute to lower combustion temperatures, which reduce the formation of NOx and particulates. The multiple injection strategy also provides an added benefit of noise reduction

Engine performance

New power bulge feature
Increased low-speed torque
New higher-peak torque ratings
Faster torque rise
Lower-rated speeds available for reduced noise and improved fuel economy

Compact size

Mounting points are the same as Tier 2/Stage II engine models

John 91黑料专区 electronic engine controls

PowerTech E engines offer electronically controlled fuel systems with improved cold-start performance, precise engine speed control, torque curve shaping and more. Because these systems have less need for redundant sensors, add on electronic governors, and shutdown devices they result in a lower total installed cost.

Additional features

Self-adjusting poly-vee fan drive
Forged-steel connecting rods
Replaceable wet-type cylinder liners
Either-side service
500-hour oil change
Gear-driven auxiliary drive
