Vac Truck For Sale3The greatest operating cost of commercial vehicles is fuel; with large diesel engines, fuel usage is proportionate to the engine size and more so when powering accessories like an hydraulic pump and blower in a vac truck for sale. Revenue can be increased by decreasing operating expenses – so fuel consumption must be considered.

Contributing Factors

To understand how to reduce fuel consumption, it is important to know what causes any unnecessary usage.

  • Rolling Resistance – Trucks consist of moving components that rub against each other and generate friction that is present from the engine to the transmission, differential, brakes, and tires. All of these create a rolling resistance requiring extra energy from the engine and more fuel to be consumed.
  • Aerodynamic Drag – In a constant state, air resistance or drag is almost non-existent. When an object moves at a certain speed, air resistance is evident; the larger the moving object, the greater the resistance due to increased air exposure. The same concept applies to trucks with a large profile and poor aerodynamics; the faster it moves, the more power and fuel is required to overcome the resistance.
  • Weight – Moving a load’s weight requires energy. The heavier the weight, the more power and fuel is needed for movement. The weight of the load is also transferred to the tires which create additional drag between the wheel and the road.

Reducing Fuel Consumption When Driving

Rolling resistance, aerodynamic drag, and heavy weight are constant variables with commercial trucks. Rolling resistance occurs from massive components; aerodynamic drag happens from large cabs and bodies; and heavy loads will always increase usage. Despite such factors, fuel consumption can be reduced while driving.

  • Constant Speed – Frequent acceleration and deceleration increases fuel usage because a decrease in momentum requires power to regain, which will increase consumption. Ideally, the driving speed should be maintained for as long as possible in order to maintain a constant momentum.
  • Avoid Stop and Go – Acceleration consumes fuel because the engine must work harder to move the truck. So try to avoid areas with many traffic lights. If stop and go is unavoidable, be light footed on the gas pedal; build up momentum gradually until the desired speed and gear is achieved.
  • Anticipate Stops – If there is traffic congestion ahead, anticipate a stop and decrease acceleration so the vehicle will stop where it should. Heavy acceleration and abrupt stopping wastes energy and reduces the life span of brake pads.
  • Scheduled Maintenance – Engine maintenance and fuel consumption are interrelated. Intake and exhaust valves with slight gaps can cause inefficiency; clogged air filters cause restricted air flow and requires more fuel to generate power. As much as possible, maintenance should be done at prescribed intervals to avoid such kinds of problems.

Even with large displacement engines, fuel efficiency with a vac truck for sale is possible. Following the above tips will help to reduce fuel consumption and provide a better profit margin every time!
