Dual Fuel Engine
The Dual Fuel engine is a kind of engine which uses a mixture of diesel fuel and gas fuel or could work off of diesel by its self. The dual fuel engine is not capable of running on gas alone. These engines do not have ignition systems and do not use spark plugs.

As diesel is not a pure gas, and it is not a pure diesel designed engine, it has some disadvantages in the department of Methane slippage as well as fuel efficiency.. For instance, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It can even be lower or higher loads.

Lift Truck Fuel Sources and Classifications
There are some applications which have proved difficult for the forklift. For instance, scrap metal is one of these issues. To be able to successfully handle items like this requires utilizing the correct type of machinery for the task.

In this write-up, the 7 major lift truck classes are discussed, including the power sources like liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to several of these particular classes. The main power sources for forklifts comprise Gasoline, Battery, Diesel, Fuel Cell and Propane.

The most popular overall are electric powered trucks, mostly in Class III, II and class I forklifts. In Classes IV and V, internal combustion trucks are more common. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, about more than 90 percent are fueled by propane.

The battery is the forklifts most popular power source. Battery powered models make up about 60 percent of the new forklifts sold within the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outdoors and indoors with no harmful emissions.
