Features
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.
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.
Mechanical rotary pump
- The timing and fuel injection pressures are optimized to maximize performance and fuel economy at a given rated speed.
2-valve cylinder head
- Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head.
