Dual Fuel Engine
The Dual Fuel engine is a type of engine which utilizes a mixture of diesel fuel and gas fuel or could operate 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 utilize 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 fuel efficiency, as well as Methane slippage.. Like for instance, 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 recycling materials handling applications which could prove extremely difficult for lift trucks. For instance, scrap metal is amongst these issues. In order to successfully handle items like this requires using the right kind of equipment for the job.

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

The most popular overall are electric powered trucks, mainly in Class I, II and class III forklifts. In Classes IV and V, internal combustion trucks are more popular. The most popular electric power source is the lead-acid battery. Out of internal combustion trucks, around more than 90% are powered by propane.

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