What does d 4d engine mean?

Answer 1

D-4D actually stands for direct Injection 4 Cylinder Common Rail Diesel Engine. Common rail diesels inject a fine mist of fuel into the engine at very high pressure. The result is the same power and refinement as a petrol engine, but with better fuel efficiency and lower emissions. This modern technology makes use of a high-pressure pump, a common rail, and computer-controlled injectors to deliver exactly the right amount of fuel to each cylinder, at precisely the right timing. It is this exact timing and fuel measurement that leads to better combustion, cleaner burning and lower emissions of harmful substances such as soot (meeting European Step III exhaust gas regulations). And it is common rail injection that ensures D-4D engines deliver the optimum in power and torque throughout the range of rpm, for better driving performance and comfort.
