Gasoline Fuel
Gasoline usage is unlikely to decline in the near future. A highly efficient combustion system is required to enhance the economy, performance and emissions of modern engines. Engines will become more complex with Boosting, Variable Valve Lift and Timing along with advanced combustion processes becoming more common. Gasoline has limitations for combustion knock and fuel quality in many regions.
FlexDI offers a truly comprehensive stratified combustion system for Gasoline applications. Variable injection strategy and phasing enables many different combustion modes including, Ultra Lean, homogenous lambda=1, stratified lean, low NOx combustion and HCCI.
FlexDI also allows high EGR combustion for enhanced fuel consumption through reduced pumping losses and higher dynamic compression ratios. FlexDI can tolerate up to 45% EGR.
FlexDI is ideal for boosted applications with lower knock and improved low speed torque capability making engine downsizing possible. Low speed driving is achieved with a unique lean-burn combustion mode vastly improving city and stop/start driving fuel economy.
FlexDI offers:
- 12% improvement in fuel efficiency with 3-way catalyst
- Reduced combustion knock & higher compression ratio
- Ultra lean-burn capability with lean NOx trap
- Enhanced boosted engine efficiency
- 'Lean' Cold start for improved emissions
- Up to 25% improvement in FC with lean NOx trap
- Advanced HCCI combustion control
- Low sensitivity to fuel quality
All at the lowest cost in class.
