Why Engine Idling is Always Bad News

Fuel economy for truckers can be affected by fuel use. One very important factor owners or operators of trucking fleets should consider is engine idling which affects fuel economy.

Engine Idling can cause engine wear and tear and bad fuel economy.How Bad is Engine Idling?

Research shows that excessive engine idling increases the amount of fuel burned and negatively affect the engine life. For example, an hour of engine idling is the same as almost 120 minutes of driving time. This will put more wear and tear on the engine over time and lead to loss of substantial fuel economy.

Excessive engine idling can result in loss of more than 700 gallons of fuel annually for each truck. The average idling that is done per day often ranges one to two hours. This can result in the loss of 2 to 4 gallons of gas. Cutting back on excessive engine idling, therefore, can save almost 4 gallons of gas each day. This, over time, will substantially improve fuel economy.

Why Idle in the First Place?

People who usually keep their engine idle do it to run their sleep berth and to prevent diesel gelling during the cold months. There are alternatives for this, however, that can be used to skip the need for engine idle.

For sleep berths, idle reduction technologies are available now to provide heating and power into trucks. Examples are battery auxiliary power systems and diesel-fueled auxiliary power systems. As for the problem of diesel gelling, this can be prevented by using additives and winter blend fuel.

Excessive idling has no benefits and can be damaging to the overall fuel economy. By lessening the amount of idle time, you can save almost 4 gallons of gas each day Skipping engine idling can lead to increased productivity and profits.for each truck in your fleet.

The dependability and productivity of your trucking fleet can be  improved by decreasing the amount of idle time for each truck. Besides increasing fuel economy, it can also increase profits too. Excessive idling, however, can lead to burned fuel and engine wear that can decrease profitability and productivity.

Downtime is critical, but it can be lessened by decreasing the amount of engine idle time. Excessive engine idling can result in the loss of gallons of gas per day. Decreasing idle time for each truck should be a priority of truck owners and operators.

Using a fuel additive that can lessen the emissions and improve fuel economy can help too. These additives can increase fuel use by improving the internal combustion process.

    I have been wondering about the positive benefits and negative drawbacks of idling diesel engines after noting that several diesel pickup owners and the county road trucks left to idle. I assumed that starters lasted longer and idling engines kept vehicles warmer in winter and cooler in summer. Extreme cold also leads to diesel fuel gelling. I also assumed that the additional fuel cost probably outweighed any wear and tear savings on the starter and that rarely does our temperature drop so low in Rains County that the gelling was a major concern. This article confirms my assumptions and points out that idling actually is harmful to diesel engines which are considerably more expensive than starters and the cost of the fuel adds up quickly. Pass this info along to your friends that think that idling is good for their diesel engines.
