You can turbocharge any engine provided you have a mechanism available to provide more fuel under boost... hence in a diesels case change the pump pressure in reference to the boost. In cases of injected engines you will have to remap the chip's or use a tool like Pete's (this is only for crdi engines).

Turbo diesels need plenty of cool air, so a RAM air intake from the front of the grille is a better idea than stock factory air box setup, also a bigger air filter goes a long way, the other factor is that turbo diesels already are well muffled due to the turbo vanes taking off most of the exhaust boom, so bypassing the muffler gives you HP and mpg gain. The best benefit to all this is that your engine runs cooler as well, almost 10c improvement in most cases.

CRDI engines develop more power but at the cost of reduced engine and pump life due to the extremely high pressure environment, also for the newer reduced pollution CRDI engines, the ring land area has been pushed right to the top and thereby far more stress and lube issues.

To turbo charge a normal diesel engine, lower end stress and EGT is two of the bigges issues, ideally, turbo diesels need enhanced cooling of the pistons so oil squirters are must, also sodium filled exhaust valves are a must for the normal than hotter exhaust, the oil pressure as well as cooling system too has to be enhanced to accomodate the extra heat and lastly, a 10-15% extra fuel is needed from the IP with a boost apparatus for the pump.

Nah the CRDe scorpio is more FE slightly and faster by 3 whole secs to 100! More drivable, better torque! What else do you want!

If i am not mistaken its available for a Endeavour

But its still Mahindra tinkering with new technologies. An insider at a Mahindra workshop strongly recommends the regular Scorpio over the CRDe

GTO,

Good point, remember, the original Scorpio engine is the modded Peugeot XUD series engine by AVL, CRDI technology deals with very high injection pressure compared to IDI and even DI. I would wait for the CRDe to accumulate 60,000 hard driven miles before passing any kind of judgement on it.

Cool How diesel ignites in a diesel engine.

hey all,
I understand that petrol cars have spark plugs to ignite the fuel but what about the diesel cars? How does the fuel get ignited in this can any one help.

Cheers.

In a diesel engine the fuel gets ignited by compressing the fuel

Read more about it here.

it is not the fuel that is compressed, it is the air entering the engine, that is compressed. the air is compressed to a very high pressure, and rusults in a very high temperature, then diesel fuel is injected into the cylinder, in the form of a very fine mist, and due to high temperature, it explodes.

there is a petes tuning box for inova... check out their website.... other stuff that can help are better air filters and a free flow exhaust....

Default More Power for Diesel cars

Hi RTech,
How can the powerchip increase the power? I heard it gives wrong signals to the ECU and increases the output. Will it not damage the ECU and reduce mileage?
