Excessive engine heat impairs fuel efficiency, decreases horsepower and ultimately lead to higher maintenance costs. Diesel engines utilize an air cooler, radiator and a hydraulic fan to control engine temperature. Under high engine loads -- the kind of loads to which full buses all over congested urban America are routinely exposed -- engine temperatures rise while fuel economy drops.
Michigan-based engine equipment manufacturer EMP's new TK retrofit unit directs cool air from an array of electrically powered, individually controlled fans, reducing the frequency of operation of the standard engine's horsepower-intensive, hydraulically-driven fan.
The TK unit also minimizes or eliminates the need for the bus engine's electronic control module (ECM) to cut back on fuel delivery and power.
The commercial grade TK Series fans incorporate brushless motors that operate on 12-volt or 24-volt power and are fully reversible -- a maintenance-saving feature for buses that are often operating in high-debris environments.
The number of cooling fans in the array, like the system itself, is customizable to suit customer requirements.
