Dual Fuel Engine
The Dual Fuel engine is a kind of engine which uses a mixture of gas fuel or diesel fuel or could run 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.

As 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 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 applications which have proved difficult for the forklift. For instance, scrap metal is one of these issues. To be able to successfully handle items like this needs using the correct type of equipment for the task.

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

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

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