Dual Fuel Engine
The Dual Fuel engine is a kind of engine which 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 working on gas alone. These engines do not have ignition systems and do not utilize 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 Methane slippage as well as fuel efficiency.. For example, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It can even be lower or higher loads.

Lift Truck Classification and Fuel Sources
There are certain applications that have proved a challenge for the forklift. Like for example, scrap metal is amongst these problems. In order to successfully handle items like this requires utilizing the right kind of equipment for the task.

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

The most common 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 common electric power source is the lead-acid battery. Out of internal combustion trucks, around more than 90 percent are propane powered.

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