1. There must be sufficient starting speed. The starting speed is high, the gas leakage in the cylinder is small, the time for the compressed air to transfer heat to the cylinder wall is short, and the heat loss is small, so that the gas temperature and pressure at the end of compression can be increased. Generally, the rotation speed is required to be above 100r/min.
2. The sealing of the cylinder should be good. This can further reduce air leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression, and the compression pressure of the cylinder must not be lower than 80% of the standard value.
3. It is required that the matching clearance between theengineand the running parts is appropriate and the lubrication is good.
4. The battery must have sufficient starting capacity, and the technical condition of the starting circuit is normal.
5. The starting oil quantity meets the requirements, the injection quality is good, and the injection advance angle must meet the requirements.
6. Use fuel that meets the requirements.
