The greater flow rate of intake air during these conditions means that a greater quantity of blow-by gases can be added to the intake system without compromising the operation of the engine. The opening of the PCV valve during these conditions also compensates for the intake system being less effective at drawing crankcase gases into the intake ...
Diesel engine runaway: Diesel engine power is governed by the amount of fuel supplied. Excessive pressure in the crankcase can force mist of engine oil into the intake manifold, which can be burned in the same fashion as Diesel fuel, thus causing runaway. One-pedal driving mode and lack of brake application in deceleration and reverse actions. [16]
In most steam engine designs there is a short time at the end of the return stroke of the piston when all the valves are shut and it is compressing any remaining steam. Water can be introduced from the boiler or in a cold engine, steam will condense to water on the cool walls of the cylinders and can potentially hydrolock an engine.
This steam can damage the catalytic converter. If a very large amount of coolant leaks into the cylinders, then the engine can suffer from hydrolock, which can cause extensive engine damage. Combustion gas leakage. When the combustion gasses leak out of a cylinder, this causes a loss of compression, leading to power reduction or rough running ...
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold. It is a ...

Although the initial wound often seems minor, the unseen, internal damage can be severe. With hydraulic fluids, paint, and detergents, these injuries are extremely serious as most hydraulic fluids and organic solvents are highly toxic. Delay in surgical treatment often leads to amputations or death. [1]
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft.
