Dual Fuel Engine
The Dual Fuel engine is a type of engine that utilizes 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 working 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 fuel efficiency, as well as Methane slippage.. For instance, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It could even be lower or higher loads.

Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which can prove really challenging for lift trucks. For example, scrap metal is among these problems. In order to successfully handle items like this needs utilizing the correct type of equipment for the task.

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

Electric powered trucks are the most popular, mainly 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. Among internal combustion trucks, about over 90% are powered by propane.

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