Dual Fuel Engine
The Dual Fuel engine is a kind of engine that uses a mixture of diesel fuel and gas fuel or can operate 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 the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from poor fuel efficiency and Methane slippage. For instance, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It could even be lower or higher loads.

Lift Truck Fuel Sources and Classifications
There are certain recycling materials handling applications which can prove very challenging for lift trucks. For instance, scrap metal is amongst these issues. In order to successfully handle items like this needs 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 some of these specific classes. The main power sources for forklifts comprise Diesel, Gasoline, Battery, Fuel Cell and Propane.

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

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