Subaru Industrial Engines introduces two big block V-Twin engines.
The 35-horsepower EH90 and 40-horsepower EH99 are designed for a wide range of applications, including concrete polishers, riding trowels, utility vehicles, zero-turn mowers, and ride-on blowers. The EH90 and EH99 are 999cc engines that feature heat-reduction technology, heavy-duty connecting rods, large crankshaft bearings, and three-ring pistons. The hardened exhaust valve and seats can handle high temperatures, which improves engine performance, efficiency and overall life of the engine Subaru says. Temperature sensors are located on the engine heads and will shut off the engine to prevent any damage from overheating due to clogged air intake valves.
