Kohler Engines Liquid Cooled Engines Available At Higher Horsepower

Kohler Engines recently announced its liquid-cooled Aegis engines are available at higher horsepower (up to 31 horsepower). Five of the six current Aegis models have been re-launched at higher horsepower with no change in engine components or displacement, said Cam Litt, product manager for Kohler Engines. "We're re-launching our Aegis models as a result of compliance with SAE J1940 standards. All of our horizontal and vertical-shaft Aegis models now exceed these standards."
The current Aegis horizontal models LH630 (22HP), LH685 (25HP), LH750 (27HP) and the LH760 (20HP) with electronic fuel injection, will now be available as LH640 (24HP), LH690 (26HP), LH755 (28HP) and LH775 (31HP) with EFI. Of the two current Aegis vertical models, LV625 (20HP) and LV675 (23HP), the LV680 (24HP) model will replace the current 23HP model.
Combining an advanced liquid-cooling design, heavy-duty air filtration system, and overhead-valve design, the quiet-running KOHLER Aegis engines offer customers peak power and torque, fuel efficiency, long engine life, and hassle-free maintenance. All KOHLER Aegis engines are offered with a three-year limited warranty for both consumer and commercial applications, said Litt. "Our warranty demonstrates the confidence we have in the design of this liquid-cooled engine and how it will perform in the field."
End-users can expect an increase in overall engine life and reliability from an advanced liquidcooling system that delivers superior engine cooling through an integrated, automotive-style radiator. With this narrow-width radiator, KOHLER Aegis engines run cool by keeping oil and cylinder head temperatures low and running temperatures consistent. The result -- oil life is significantly extended and internal engine wear is reduced.
Another KOHLER Aegis advantage is a heavy-duty air cleaner system, standard on horizontal shaft models, with a filtering area of 838 square inches. This system features a reliable two-stage filtration system. The main filter (5 micron) traps the dirty air, while the inner filter (8 micron) protects the carburetor from contamination during main filter servicing.
Also, the air cleaner's ejector valve continuously collects and discards trapped dust. As an option, customers can install a filter minder, either direct or remote mount. This vacuum-type gauge detects when air inlets become restricted and alerts the machine operator that it's time to service the air filter.
In addition, the footprint for KOHLER Aegis is interchangeable with that of the popular KOHLER Command model line, assisting OEMs in conveniently fitting the engine within new and existing applications. Contributing to optimum power and torque, KOHLER Aegis engines are designed with large displacements, meaning that the versatile engines make easy work of long and rigorous commercial, construction and industrial applications.
Many of the features and design elements in KOHLER Aegis engines are also common on the KOHLER Command engine line. End users will reap many benefits from field-tested features, such as:
overhead valve technology for fuel efficiency, power and virtually no carbon build-up;
full pressure lubrication and a full-flow, spin-on oil filter for even and continuous oil distribution and extended maintenance intervals;
12-volt, solenoid-shift starter for reliable, easy starting in all types of weather;
hydraulic valve lifters for minimal operation noise, no lash adjustment, no power loss and low maintenance, and
cast-iron cylinder liners for reliability and long life.
