Lowering the rpm's will decrease power. This rpm for this speed sounds normal, so why are you trying to lower it. Fuel economy? The engine may work harder at a lower rpm and actually use more fuel. You can lower the rpms by changing the rear axle ratio. This can be done in 2 ways. Remove and replace the differential with a different ratio unit, or change the size of the rear tire/wheel assembly. Going to a larger tire will decrease the rpms, but not by much and if will cause the speedometer to be off, and possibly effect the computer settings. One other way is to install an overdrive unit, which would be very costly.
A diesel has more power and torque at lower revs. Petrol engines need higher speed to develop power.
The difference between diesel and high speed diesel is that high speed diesel has special cleaning detergents added to it. These detergents clean the injectors, which makes the vehicle run better.
what is calorific value of high speed diesel ? what is calorific value of high speed diesel ?
Speed (of the wave) = wavelength x frequency. Therefore, since the speed usually doesn't change much, longer wavelength means lower frequency.
Diesel produces high levels of torque at lower RPMs, making it much more ideal for pulling heavy loads.
