One significant trend is engine downsizing coupled with turbocharging. Smaller, turbocharged engines can be used to raise fuel economy while meeting or exceeding the power and torque of larger engines, allowing engine downsizing and improved fuel economy with little or no performance compromise. of new gasoline-fueled LDV sales.

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.

bar decreases the BSFC (brake specific fuel consumption) up to 14% compared to the air-hybrid engine, while resulting in a simultaneous increase in the engine’s power BMEP (brake mean effective pressure) by 140%. Key to Scuderi’s split-cycle design is that it fires after top dead center. Earlier post.). Earlier post.).

Cummins made extensive use of aluminium as well as space-saving design features for new engine weight control. Lightweight steel pistons provide reduced friction & compression height with increased power density. Exhaust system configuration. diesel weighs 362 lbs (164 kg), while the ECS weighs 152 lbs (69 kg).

CO 2 emissions and fuel consumption have been cut by 13% compared to the predecessor engine, while peak torque and peak power have been increased by up to 33%. The structural design considers the engine’s use in a variety of vehicle applications, allowing minimum integration effort and consistent part interchangeability. The all-new 1.6-liter,
