Dual Fuel Engine
The Dual Fuel engine is a kind of engine which uses a mixture of gas fuel or diesel fuel or can operate 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 fuel efficiency, as well as Methane slippage.. Like for instance, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be lower or higher loads.

Lift Truck Fuel Sources and Classifications
There are some recycling materials handling applications which could prove really difficult for lift trucks. Like for instance, scrap metal is one of these issues. To be able to successfully handle things like this needs utilizing the right kind of equipment for the task.

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

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

The most common power source for lift trucks is battery. Battery powered models make up around 60 percent of the new forklifts sold within the United States. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be utilized outside and inside with no harmful emissions.
