Do not directly turn on the engine. Pay close attention and look carefully at the condition of the engine’s appearance. Make sure that the machine is really safe to turn on. Checking the condition of the engine from outside appearance includes precautions for an accident. To avoid the accident, you need to service your car, therefore visit our website and get our pick up and drop of mot service.
Turn on the Engine
Turn on the engine at the stationary rotation. Then add the spin a few minutes later if necessary.
Do not start the engine directly at high speed, this is to avoid wear because lubrication has not yet reached all engine components.
We can analyze engine damage as long as the engine is on. Consider the following three things:
Explosion due to burning of fuel (gasoline or diesel). Normal engine, the blast sound is flat. On machines that are not normally combustible, of course the opposite, uneven and jerks occur every few seconds. The sound of a gasoline engine will be smoother compared to diesel or diesel engine.
A vibration of engine components is an abnormal engine sound. These vibrations can occur because of loose bolts or nuts, broken components, or even broken. These sounds are very different from the sound of burning fuel.
Friction components that are not lubricated with oil can cause unusual noise. Sounds due to friction can arise on the level of a carburetor gas wire system that is not well lubricated. This sound can also arise due to piston friction with the cylinder wall, or friction in the piston.
Leaking gas flow can cause abnormal sound. The sound is in the form of a loud hiss.
The leakage usually occurs in gas lines that enter the cylinder.
Even abnormal sounds can occur due to a knock between two engine components that are quite loud. For example, in the valve gap that is too large, the crankshaft bearing or piston pen is loose.
The noise caused by an electric spark can occur. The sound is caused by the spark Sabunga fire from electricity has a leakage current or a short connection occurs.
