crdi gives more mileage
Yes, the indirect injection is more fuel efficient because it provides stability to the engine.
in crdi engine using a pump is provide more pressure and powerful than ordinary pump. . it silent in operation and no priming.
When it comes to fuel efficient and luxury cars the best bet is to compare hybrid-engine designs. More and more luxury car companies are now coming out with fuel efficient hybrid-engine designs.
2.5 liter engine is smaller and more fuel efficient. 3.5 liter engine is a strong engine with better acceleration, but is less fuel efficient
They certainly are. Using them together with carburetted engines can be a bit tricky, and usually the compression has to be lowered when compared to a naturally aspirated engine.
The smaller the engine the less fuel it will use. But then again an engine too small for the application can use more fuel than a larger engine that is appropriate for the application.
People often think of compact cars when they consider fuel efficient cars. But there are many midsize cars and SUVs that are fuel efficient. In choosing a car that will have good gas mileage, also consider the size of the engine and the vehicle size. An engine that is too small for the size of the vehicle may save you on fuel but cost more on engine repair or replacement.
A four-cylinder engine does not require as much fuel as a six-cylinder, which requires half again as much fuel every time the pistons fire. A six-cylinder is more powerful, too, and accordingly uses more fuel. Four-cylinders are more economical, and if they are properly maintained, are more efficient.
The EDC or electronic diesel control system monitors and controls the rate of fuel injected into the CRDi in late model diesel engines. It makes diesel engines operate more efficiently.
Common Rail Direct Injection (CRDI) Did you ever shy away from buying a Diesel car thinking that you would be buying a taxi? If yes then you can rethink your decision as CRDI engines are all set to revolutionize the way one looks at Diesel cars. CRDI engine fitted cars offer 25% more power than the normal direct injection engine with a superior pickup and torque offering sometimes up to 70% more power than the conventional diesel engines. They are smooth less noisy and immensely fuel efficient giving around 24 kilometers to a liter of Diesel. The fact that Diesel is cheaper than petrol in India further attributes greatness to the engine. In a CRDI engine, a tube or a common rail connects all the injectors and contains fuel at a constant high pressure. This high pressure in the common rail ensures that when injected, the fuel breaks up into small particles and mixes evenly with the air, thereby leaving little un-burnt fuel thus reducing pollution. The common rail principle has been used to cut out the noise factor which used to be associated with Diesel engines; the technology has been pioneered by the Fiat group, only to be adopted by other automobile companies around the world. Like all good things in life, these engines also come at a price; they are at least 25% more costly than the conventional engines. They also require a higher degree of maintenance and spares aren't cheap also.
The diesel is more efficient but more expensive to build.
