Only the simplest ones.
All modern fuel injection systems will use some kind of computer "chip" to calculate optimum fuel insertion, whether they are gasoline or diesel.
Older gasoline engines use electrical ignition, so maybe these are not "electronic".
The only engines using no electricals while running are basic diesels, such as older tractor, forklift and earthmover engines, especially those designed for hazardous atmospheres such as mines.
Completely electricals-free engines would be diesels with compressed air start.
Mazda cars require gas for their engines, not diesel. They also have hybrid vehicles, which run on both electricity and gas, but not diesel.
GAS OR DIESEL?
NO, gas parts and diesel parts do not need to mix.
No you can not use gas engine oil in diesel engine oil because processing of diesel engine is different from gas engine oil. If you use this then it damage your vehicles.
Propane gas conversion kits can be obtained from Nash Fuels and Duda Diesel. They can also be obtained from specialty stores that specialize in propane tanks and parts for vehicles.
Yes, car engines can be diesel or gas. Some models of cars are available with either type. Gas is more widespread but there are a few VW cars run on diesel. You can't hear them much but they do have diesel vehicles available.
Motor vehicles are powered by an engine or motor (gas, diesel, electric, etc.). Horse-drawn vehicles are powered by a horse.
Gas is 12 volts and diesel is 24 volts
These vehicles are better for the environment. There are not as many places to fill them up so mobility is limited.
No, you cannot convert a gas engine to a diesel engine. A diesel requires much stronger parts.
diesel, unleaded, leaded, also some hydrogen and e85 eathonol vehicles exist
Both are internal combustion engines that can be used to drive vehicles, generators, etc. One is fuelled by diesel, and the other one uses gas (USA), petrol (UK). Both diesel and petrol is derived from refined crude oil.
