Perkins 1004G14 / 1004TG14 / 1004TAG14 Diesel Engine

Perkins 1004TAG14 is inline four-cylinder, water-cooled four-stroke direct injection diesel engine. Displacement 3.99L, bore × stroke:100 mm × 127 mm, Quadram spherical combustion chamber. Adopts turbocharged + air-to-air intercooled intake system, fitted with electronic governor, designed for fixed 1500 rpm constant-speed operation (50Hz power matching).

Electronic governor realizes high-precision speed control, small speed fluctuation during sudden load change. Air-to-air intercooler effectively lowers intake temperature, improves power density and reduces exhaust temperature. Single-side maintenance layout, convenient daily inspection and filter replacement. Standard SAE installation interfaces for generator and water pump transmission connection. Suitable for outdoor, dusty and long-time continuous working conditions. Available as complete engine assembly. Each unit passes bench hot test before delivery to guarantee steady speed, stable power output and reliable sealing performance.

Main Matching Equipment

85kW stationary diesel generator sets (50Hz)

40kW stationary diesel generator sets (50Hz)

65.7kW stationary diesel generator sets (50Hz)
