A motor engine uses fuel to run a vehicle. The fuel used by the engine also results in considerable emissions. These fuel emissions are damaging to the atmosphere, and also increase the fuel costs. During long journeys, people sometimes need to stop their cars and vans, and keep the engines idling. This enables them to use the air conditioner and lighting inside the car, while being stationary. This is also the case with commercial vehicles such as carriers. However, this too results in fuel emissions and a drastic increase in cost and pollution. Therefore, you need to use alternative technology. The best fuel saving technology available uses an Auxiliary Power Unit to reduce fuel emissions. If you visit a good retailer, you can get a Carrier APU installed at a significantly low price.

Carrier trucks burn a large amount of fuel, due to the distance they travel daily. A Carrier APU can reduce the emissions by more than 50% on a daily basis. A good APU unit is weatherproof, and hence, does not get affected even in heavy rain, snow or extremely hot weather. An effective APU for carriers is usually mounted on the truck rail, and fitted inside an enclosure. The enclosure is made of stainless steel and thus, resistant to corrosion as well. The APU uses the fuel supply of the truck, but at a far lower rate than the normal engine. Usually, the main truck engine is started using the APU. This ensures that the fuel supply function becomes effective immediately. An APU also helps to maintain a low temperature in the engine, and thus prevents it from overheating.

When the carrier is brought to a halt, the driver can switch off the main engine and keep the Carrier APU running. This helps him to keep the AC and lights on, while saving enormous amounts of fuel. Modern APUs possess their own heating, cooling and ventilation systems built internally. These systems aid further, in the temperature control process of a stationary vehicle.

Auxiliary Power units, used today, are almost entirely automated. They have auto start controls for low voltage, coolant temperature, bunk temperature, etc. The coolant temperature auto start mechanism is the most important, as it is this mechanism that controls the air conditioning inside the vehicle. The mechanism responds automatically to changes in the external weather conditions, even if the APU controls are not adjusted manually. The low voltage auto start helps the vehicle start its engines smoothly, reducing the risk of an alternator failure. Moreover, even if operated manually, the microprocessor interface is a one touch interface and easy to use.

The Carrier APU units, used today, can be installed very quickly, regardless of the make and design of your vehicle. The APU can work extremely well, for at least one year, without need of special servicing. Also, normal service intervals of the APU match the maintenance intervals of the truck. This means that you can carry out complete maintenance of your vehicle at one time, and save on overall costs.
