Dual Fuel Engine
The Dual Fuel engine is a type of engine which utilizes a mixture of gas fuel or diesel fuel or can work 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 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 Methane slippage as well as fuel efficiency.. For instance, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It can even be greater on lower loads.

Lift Truck Fuel Sources and Classifications
There are some recycling materials handling applications that could prove really difficult for lift trucks. Like for example, scrap metal is amongst these problems. In order to successfully handle items like this requires utilizing the correct type of machinery for the job.

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

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

The most common power source for lift trucks is battery. Battery fueled units make up around 60% of the new forklifts sold in the USA. Their benefits include: quiet operation, less maintenance requirements, the ability to be utilized inside and outside with no harmful emissions.
