Old ones, cable drive tach. New ones, crank sensor.
Diesel engines have much more torque at low rpm.
(i) Reciprocating spark ignition engine 60 to 90 rpm.(ii) Rotary spark ignition engine 150 to 180 rpm. (Hi) Diesel engines with glow plugs 60 to 140 rpm. (iv) Diesel engines without glow plugs 100 to 200 rpm.
Yes. You will go very slow since most diesel engines make low rpm's. If you mate a gasoline engine to a diesel transmission you will go very fast since most gasoline engines make high rpm's. Transmission adapter plates and other modifications can be made but be prepared to fail
Horsepower is calculated from RPM and torque. The higher the RPM you can sustain an engines torque at, the higher the Horsepower. Horsepower and Torque are always the same amount at 5250 RPM with all but diesel powered engines. Also the more rotational mass you can spin at a higher rpm, the more energy it poseses.
Diesel engines get better fuel economy because they do not need to burn as much fuel as a gas engine to get the same power. By design a supercharged engine will produce more power whether it be gasoline or diesel. A diesel engine has more torque at lower rpm than gas engines and therefore uses less fuel. The correct answer is YES.
Diesels are not gasoline engines. On a gas engine you are looking for horsepower because they don't have much torque. Horsepower comes from high RPM. Diesel operators look for torque, which on a diesel comes at low RPM. I run a Cummins ISX. Its maximum RPM seems to be somewhere around 1700-1800; the truck runs best around 1200-1300.
Well this all depends on what type of engines are supplied in these buses. Usually buses use diesel due to the high weight load that that are put on the engines. Diesel engines have better compression and can usually provide more torque to do work with all those people on board. Here is a good read on Diesel engines....(link)
Diesel engines run on diesel fuel. Gasoline will destroy a diesel engine.
Atlantis Diesel Engines was created in 1979.
Diesel engines on boats are a waste of money.
It is 3600 RPM
In a nutshell, you have highway engines, off-road engines, marine engines, and power generation engines. While the different types might be built on matching blocks, where they're cruised at RPM-wise, the amount of power they produce, and their peak powerbands will vary, as well as the emissions standards which they're subject to.
