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

Because the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from Methane slippage and fuel efficiency. Like for example, 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 certain applications which have proved difficult for the forklift. Like for instance, scrap metal is one of these issues. In order to successfully handle things like this needs utilizing the right kind of machine for the task.

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

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

The battery is the forklifts most common power source. Battery powered units make up about 60% of the new forklifts sold within the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be utilized outdoors and inside with no harmful emissions.
