PowerTech M
4.5L Diesel Engine
Power Ranges
4.5L: 56-74 kW (75-99 hp)
2-Valve Cylinder Head
Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head.
Mechanical Rotary Fuel Pump
The timing and fuel injection pressures are optimized to maximize performance and fuel economy at a given rated speed.
Fixed Geometry Turbocharger
Fixed geometry turbochargers are precisely matched to the power level and application.
Turbocharged
In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air
is supplied into the combustion chamber allowing a corresponding increase in fuel injection,
which results in greater engine output.
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.
Compact Size
Mounting points are the same as Tier 2/Stage II engine models.
