Changfa's newly developed multi cylinder diesel engine for construction machinery adopts advanced turbocharging and combustion matching technology, with good economic performance and meeting the national four stage emission requirements; The key components, analyzed by computer CAE technology, have the characteristics of high reliability, low fuel consumption, and easy maintenance, making them an ideal power source for supporting engineering machinery and equipment.

1. Specially developed for the characteristics of construction machinery, it meets the power requirements of 15-300 horsepower range construction machinery, with rich configuration, low-speed high torque, strong idle load capacity, low-speed torque reserve of up to 30%, and strong horsepower.

2. Adopting advanced domestic air heaters and high-power reducers to meet the requirements of use in cold regions. Fast acceleration, it takes 3 seconds to reach the calibrated speed after idle loading.

1. 2000 sets of reliability tests with no faults and a service life of 1500 hours.

2. The installation interface is consistent with the products on the national three platform, making it easy for customers to upgrade and replace.

The National IV turbocharged intercooler model adopts a non road specific electronic control high-pressure common rail system, which flexibly controls the fuel injection pressure to achieve multiple injections. Combined with the optimized shallow pot combustion chamber, it effectively improves the performance of the diesel engine and reduces emissions.
