  2. Crankcase dilution - Wikipedia

    en.wikipedia.org/wiki/Crankcase_dilution

    Engines that run on biodiesel have the same problem as regular fuel engines. The biodiesel fuel finds its way into the crankcase of the engine and mixes with the lube oil. When biodiesel leaks into the crankcase, it has more problems than with more traditional fuel. The biodiesel has a higher boiling point than regular fuel and is less likely ...

  3. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    Fuel demand is low at idle and there is more than enough manifold vacuum to draw sufficient fuel for combustion, even if the fuel pump is switched off. Gasoline engines that are much smaller than the typical automotive engine are usually carbureted for economic and engineering reasons. Dieseling can occur in such engines.

  4. Diesel cycle - Wikipedia

    en.wikipedia.org/wiki/Diesel_cycle

    However, a real diesel engine will be more efficient overall since it will have the ability to operate at higher compression ratios. If a petrol engine were to have the same compression ratio, then knocking (self-ignition) would occur and this would severely reduce the efficiency, whereas in a diesel engine, the self ignition is the desired ...

    I am looking at a Chevy Silverado 3.0 turbo-charged diesel. I was wondering if there are any problems with these engines and how reliable they are?

  6. Diesel engine - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine

    1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

  7. Pre-ignition - Wikipedia

    en.wikipedia.org/wiki/Pre-ignition

    A lean fuel mixture or excessive amount of oxygen in the combustion chamber; An engine that is running hotter than normal due to a cooling system problem (low coolant level, slipping fan clutch, inoperative electric cooling fan or other cooling system problem) Auto-ignition of engine oil droplets (Can be solved by using an oil catch tank) [3]

  8. Wet stacking - Wikipedia

    en.wikipedia.org/wiki/Wet_stacking

    Cold weather running or other causes that prevent the engine from reaching proper operating temperature can cause a buildup of fuel due to incomplete burn that can result in 'wet stacking'. [2] [3] In diesel generators, it is usually because the diesel engine is running at only a small percentage of its rated output. For efficient combustion, a ...

  9. Vapor lock - Wikipedia

    en.wikipedia.org/wiki/Vapor_lock

    Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
