Current and Future Development Engine Details about Diesel Marine Aeronautical Engine

As of 2008, may common rail and unit injection systems alreaky employ new injectors using stacked piezoelectric wafers in lieu of a solenoid, giving finer control of the injection event. Variable geometry tubochargers have flixible vanes, which move and let more air into the depending on load. This technology increases both performance and fuel economy. Bost lag is reduced as turbo impeller inertia is compensated for.

Accelerometer pilot control (APC) uses an accelerometer to provide feedback on the engine's lovel of noise and vibration and thus instruct the ECU to injection the minimum amout of fuel that will produce quite combustion and still provide the required power (especially while idling). The next generation of common rail diesels is expected to use variable injection geometry , which allows the amount of fuel injected to be varied over a wider range.

Partially in the United States, coming tougher emission regulations present a considerable challenge to diesel engine manufactures. Ford's Hy Trans Project has developed a system which starts the ignition in 400 ms, saving a significant amount of fuel on city routes, and there are other methods to achieve evern more efficient combussion, such as homogeneous charge compression ignition, being studied.
