The twin-Cylinder air compressorserves as the core power component of commercial vehicle pneumatic systems. Key specifications are as follows:

Core Function

Driven by the engine crankshaft via gears, it compresses external air and delivers it to the air TANK. This provides high-pressure air (typically 0.7-0.8MPa) to power pneumatic systems including the vehicle's braking system (air brakes), clutch assist, and door controls.

Compatible Models and Engines

Compatible Engines: Weichai WP10/WP12, Sinotruk MC11, and other heavy-duty diesel engines

Compatible Models: Sinotruk Howo, Sandaika, Shaanxi Delong heavy-duty trucks (particularly suitable for dual-circuit brake systems)

 (Model VG1246130001) 

Product Features

Structure Type: Dual-cylinder reciprocating piston compressor. The dual-cylinder design enhances air output to meet heavy-d

uty vehicles' high-flow pneumatic demands. Integrated top pressure regulator automatically controls discharge pressure, preventing overpressure risks.

Drive & Installation: Driven directly by engine power via front-end gears meshing with the engine crankshaft gear. The housing is bolted to the engine block side for a compact layout.

Cooling & Lubrication: Some models integrate an oil cooling channel, utilizing engine oil for compressor lubrication and cooling. An oil-air separator is installed at the exhaust port to reduce oil residue in compressed air.

Maintenance Key Points: Regularly clean the air filter (to prevent debris from entering the cylinder and wearing the piston). Check the pressure setting of the pressure regulator. If discharge volume is insufficient, inspect the piston ring seals or cylinder wear.
