To comply with environmental regulations in recent years, automotive manufacturers have decreased vehicle engine revolutions at rest to reduce carbon emissions. Lowered idle RPM has indeed led to fewer emissions—a fine trade-off for most consumer vehicles in typical situations. However, for specialty vehicles with work to do at idle, low RPM can cause problems.
APS high-idle controls increase engine-idle RPM to ensure consistent electrical power to the aftermarket systems required to get the job done.
Clients often combine an APS high idle engine switch with a high output alternator and custom alternator bracket—or dual alternator bracket kit—for a complete package that delivers high power regardless of whether the vehicle is in motion or at rest.
High idle engine switches—also called high idle controllers, or high idle kits—are used in a variety of industries in which end-users require high power from a vehicle when it’s not in motion. Common applications include armored and security vehicles, work trucks, buses and motor coaches.
