Dual Fuel Engine
The Dual Fuel engine is a type of engine that utilizes a mixture of diesel fuel and gas fuel or could run 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.

Because 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.. For instance, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It can even be greater on lower loads.

Lift Truck Classification and Fuel Sources
There are some applications which have proved difficult for the forklift. Like for example, scrap metal is amongst these problems. To be able to successfully handle items like this needs utilizing the correct kind of equipment for the job.

In this write-up, the 7 major lift truck classes are discussed, including the power sources such as 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 Diesel, Gasoline, Battery, Fuel Cell and Propane.

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

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