What is the reason why the Changchai 1115 diesel engine cannot accelerate?

[VonCole]

The reason why the Changchai 1115 diesel engine cannot accelerate may be due to fuel line blockage, insufficient fuel supply; low rail pressure caused by injector leakage, etc. Check the ignition system: Mainly check whether the ignition energy is too weak and whether there is intermittent ignition failure. This is directly related to the performance of spark plugs, high-voltage wires, and ignition coils. Also, check whether the ignition timing is normal, as both advanced and retarded timing can lead to poor acceleration. Check the electronic fuel injection system: Check whether the fuel pressure is too low, whether the fuel filter is clogged, and whether the injector is obstructed or leaking, causing poor fuel spray and atomization. Additionally, check whether the air filter is severely clogged.
