Advantages of L Automotive Engine

1. The cylinder bore adopts a platform mesh honing design, the perfect geometric structure effectively prevents oil leakage, and adopts advanced technologies such as new piston ring components and gasket crimping molding to reduce oil loss.
2. The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
3. Forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.
