Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which can run on a mixture of diesel fuel and gas fuel or it can work on diesel fuel alone. Duel Fuel engines are not able to run on gas alone since they do not posses an ignition system, nor do they possess any 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 could 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 Classification and Fuel Sources
There are some recycling materials handling applications which could prove really difficult for lift trucks. Like for example, scrap metal is amongst these problems. To be able to successfully handle things like this requires using the correct kind of equipment for the task.

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

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

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