Dual Fuel Engine
The Dual Fuel engine is a kind of engine which uses a mixture of gas fuel or diesel 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 utilize spark plugs.

Since 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 lean-burn, spark-ignited engine at 100% load. It can even be lower or higher loads.

Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that can prove very difficult for lift trucks. For instance, scrap metal is one of these problems. In order to successfully handle items like this requires using the right type of machine 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 particular classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Fuel Cell and Propane.

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

The battery is the forklifts most popular power source. Battery fueled models make up approximately 60% of the new forklifts sold within the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used inside and outside with no harmful emissions.
