  The GL (Lean Burn) fuel system and high turbulence combustion chamber provide excellent fuel efficiency and optimum combustion stability. VGFs optimum BMEP results in better service life for key components and maintenance intervals. The patented high turbulence combustion chamber allows ability to burn lean air fuel mixtures with an open combustion chamber. This produces low emissions across engine load and speed range. It also provides lower fuel consumption, which is typically 91% of life cycle costs. The low fuel pressure GLD model has draw-thru carburetion capability which increases application potential. Individual, four valve, water cooled cylinder heads ensure optimum performance and reliability. Cooler cylinder head operation results in longer valve train component life and lower maintenance cost. The VGF is adaptable to natural gas and propane as well as digester gas and even landfill gas.

  Main bearing journals are align-bored to ensure proper alignment with the crankshaft. This reduces stress distortion, and increases bearing life. Cross bolting of the main bearing caps to the crankcase provides a rigid frame for support and alignment of the crankshaft. T-style, cross drilled lubrication passages provide full 360 degree lubrication to the connecting rod. The improved cooling and a thicker, stronger design help increase component life. Large radius fillets minimize crankshaft stress between the journals and crank throws. Steel backed bearings with an alloy overlay combine high load bearing capability with excellent corrosion resistance for long life. Ungrooved lower main bearings and continuous 360 degree coiling from the T-drilled crankshaft provide a 40% increase in load carrying capacity. Cylinder liners are made of heat treated bainite cast iron, with greater strength for less flexing and longer wear. New three-ring piston offers better expansion characteristics at the crown and greater strength in the pin boss.

  Cooling passages direct water precisely where needed for component cooling and thermal stability. Yet, mechanical strength is not sacrificed due to the location and size of these passages. The passages are drilled, rather than cast, to ensure consistent size and location. All surfaces of the connecting rod are machined. This process removes stress risers caused by the forging process and controls the weight of the component. Not only is the rod structurally sound, but variation of the rotating masses is minimized. Bore cooling passages direct water to each valve seat to reduce operating temperatures. Reducing temperatures and maintaining thermal stability increases component life. ATGL top-end overhauls of up to 30,000 hours have been achieved. Turbochargers have a water cooled center section to improve bearing cooling for maximum operating life.
