Four-cycle, 4-cyl Vortec 3000 is available in factory-installed multiport fuel injection gasoline version, and gaseous fuel version with 35 kW genset rating. With MPFI version, fuel injectors are positioned in intake ports of cylinder head and spray fuel on back of intake valves, promoting complete combustion. On high-output gaseous fuel engine, cylinder head combines with 10.5:1 compression ratio, resulting in ratings of 65 and 60 hp at 1,800 rpm with propane and natural gas, respectively.

Factory-Installed MPFI Gasoline and High-Output Gaseous Fuel Versions Now Available

PONTIAC. MICH - GM Powertrain announced enhanced versions of the Vortec 3000 industrial engine for 2006. These versions offer factory-installed multiport fuel injection (MPFI) for a gasoline version and a high-output gaseous fuel version with increased horsepower and torque - and a 35 kW genset rating at 1800 rpm. The engines are designed for a variety of mobile and stationary applications.

The Vortec 3000 engine is the most powerful four-cylinder gasoline engine available in the industrial market. MPFI offers improved fuel economy, reduced emissions, smoother operation and instant starting. With low emissions and smooth performance in a compact package, all versions of the four-cycle, four-cylinder Vortec 3000 deliver the power and torque of many larger-displacement six-cylinder engines.

"The enhancements to the Vortec 3000 reinforce its adaptability and value for any industrial application," said David P. Garrett, engineering manager for GM Powertrain OEM sales.

The addition of factory-installed multiport fuel injection adds convenience to the Vortec 3000 gasoline engine, since the injection system no longer requires OEM installation. And because the injection system promotes hotter, more complete combustion and delivers more precise ignition, idle quality and operational smoothness of the engine are enhanced.
