STUDY ON AUTOMOBILE HIGH SPEED DIESEL INJECTION (HSDI)

Abstract

The efficiency of combustion in I.C. engines depends upon the atomization of the fuel and the thoroughness of mixing with the air. However, after the end of compression stroke, the fuel is injected into the combustion chamber and mixed with compressed air and burnt. The present situation, the passenger cars with Direct Injection (DI) Diesel Engines have the lowest fuel consumption, but the greatest problems towards
the emission legislation to the current lack of effective exhaust after treatment methods and increasing weight. As per study it was notice that EURO-III, norms was achievable for all but the heaviest vehicles, where as EURO-IV is only feasible for the lightest vehicle. Therefore, overload capacity is a biggest question special reference to Heavy Commercial Vehicles.
