Advantages of EQB190-20 Automotive Engine

  • Lower fuel consumption: Originated from the United States CMS advanced design and superior manufacture, lower 20% oil consumption than congeneric Chinese products.

  • Strong power, the design of exhaust bypass valve makes low speed performance more perfect and better dynamic performance.

  • Excellent reliability, Cylinder block and head using integrated design, to stop the engine leaking and oil leakage phenomenon, engine parts are Less 40% than other similar engine, greatly reduce the failure rate.

  • Lower maintenance and repair costs, Fewer parts quantity and lower use fault Make the engine comprehensive maintenance cost greatly reduced and maintenance time than similar type save 50%.

  • Excellent cold start performance, equipped with air suction electric preheater and 6.6 kw power starter, Completely improve the cold start performance of the engine. Through the arctic village-MoHe of China-36。C extreme low temperature validation.
