Dual Fuel Engine
The Dual Fuel engine is a kind of engine which uses a mixture of diesel fuel and gas fuel or can run 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 example, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent 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 difficult for lift trucks. For instance, scrap metal is among these issues. In order to successfully handle things like this requires using the right kind of equipment for the task.

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

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

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