This business unit provides engine components to major automotive engine manufacturers, including hydraulic
valve lifters, lash adjusters, roller tappets and roller rocker arms.
When commanded by the powertrain control computer, the solenoids direct oil to
valve lifters equipped with the switching mechanism.
The hydraulic
valve lifters, which have been used on Kohler engines since the late 1980s, are also a key service feature, as they eliminate the need for valve adjustments over the life of the engine.
To effect deactivation, there are special two-stage hydraulic
valve lifters that have both inner and outer bodies.
Other features of the powertrain include hydraulic
valve lifters, a Bosch alternator and electronic fuel injection speed governing.
The engine has hydraulic
valve lifters, Cull pressure lubrication with oil cooler and a Nelson heavy-duty air cleaner.
The Aegis engines, which were initially developed from the platform of Kohler's Command engine line, incorporate a range of premium features, including overhead valve technology, a full pressure lubrication system with a full-flow, spin-on oil filter; a 12 V, solenoid-shift starter; hydraulic
valve lifters; an aluminum block with cast iron cylinder liners.
The engine's hydraulic
valve lifters stay in constant contact with the push rods, providing constant power throughout the life of the engine and eliminating valve lash adjustments and noise caused by improper valve clearances, the company said.
Lombardini's CHD series of diesel engines has been updated with the addition of hydraulically actuated
valve lifters, which reduce engine noise and required maintenance, the company said.
A Kohler exclusive for an engine this compact, according to the company, are hydraulic
valve lifters, which provide consistent power throughout the life of the engine.
