Dual Fuel Engine
The Dual Fuel engine is a kind of engine that utilizes a mixture of diesel fuel and gas fuel or could work 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 Methane slippage as well as fuel efficiency.. Like for example, the fuel efficiency can 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 Fuel Sources and Classifications
There are some applications that have proved a challenge for the forklift. For instance, scrap metal is amongst these problems. In order to successfully handle items like this needs using the right kind of machinery 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 several 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 popular, mostly Class I, II and class III forklifts. Internal combustion engines are more common in Classes V and IV. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, around over 90% are powered by propane.

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