Dual Fuel Engine
The Dual Fuel engine is a kind of engine that uses a mixture of gas fuel or diesel fuel or can work 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 utilize spark plugs.

Because the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from poor fuel efficiency and Methane slippage. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be greater on lower loads.

Lift Truck Fuel Sources and Classifications
There are certain recycling materials handling applications which could prove extremely challenging for lift trucks. For example, scrap metal is among these issues. In order to successfully handle items like this requires using the correct type of machine for the job.

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 consist of Battery, Diesel, Gasoline, Propane and Fuel Cell.

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

The most popular power source for lift trucks is battery. Battery fueled models make up roughly 60% of the new forklifts sold in the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outdoors and indoors with no harmful emissions.
