Fine tuning and testing

The engine may be mechanically complete, but it needs to be fine tuned and tested. First of all, the block and the moving parts are rechecked for irregularities and alignment. Before the engine starts up for the first time, the timing of the camshaft is set up to the precisely specified timing and every moving part is carefully lubricated. There are several standard tests that every engine needs to pass, which are as follows:

• It needs to behave as expected on both minimum and maximum operating pressure
• The engine crank is stress-tested on the maximum testing pressure of 8 bars
• Once the mechanics are checked, the engine is given a few spins from the silicon lubricant can. After this the engine is left to run on approximately 100 rpms for a few minutes, so that the lubrication evenly distributes throughout the system.
• The engine needs to achieve the speed standard on 4 bars and it's one more time revved up to its maximum on maximum pressure to ensure that all tubings are gripping perfectly.
• The engine is then tested for efficiency. It needs to be able to run for a specific time on a specific pressure on a specific volume of air. This is done to check for the smallest leaks in the system.
