This provided a simple, adequate solution to the dieseling problem. Dieseling (in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake) can also occur in diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder. A structurally failing diesel engine will ...
Many high-performance aircraft however suffer extreme overheating problems when idling on the ground - a mere seven minutes for a Spitfire. [6] This is similar to Formula 1 cars of today, when stopped on the grid with engines running they require ducted air forced into their radiator pods to prevent overheating.
Hot-bulb engine (two-stroke). 1. Hot bulb. 2. Cylinder. 3. Piston. 4. Crankcase Old Swedish hot-bulb engine in action. The hot-bulb engine, also known as a semi-diesel [1] or Akroyd engine, is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb ...
Sometimes these air pockets can get trapped in the engine's coolant thermostat, causing it to stay closed and cause further overheating, thereby creating more voids between the gasket and the engine. Other times these air pockets can also cause the engine to expel coolant into the overflow or expansion tank , thereby reducing the amount of ...
In a diesel engine, the torque and the rotational speed are controlled by means of quality torque manipulation. This means that, with each intake stroke, the engine draws in air which is not mixed with fuel; the fuel is injected into the cylinder after its contents have been compressed during the compression stroke. The high air temperature ...
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 ...
That was considered normal, and at the time, most noted mountain roads had auto repair shops to minister to overheating engines. ACS (Auto Club Suisse) maintains historical monuments to that era on the Susten Pass where two radiator refill stations remain. They have instructions on a cast metal plaque and a spherical bottom watering can hanging ...
In a diesel engine, a glow plug (also spelled glowplug) is a heating device used to aid starting of the engine in cold weather.This device is a pencil-shaped piece of metal with an electric heating element at the tip.
