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

Lift Truck Fuel Sources and Classifications
There are certain applications that have proved difficult for the forklift. Like for instance, scrap metal is among these problems. To be able to successfully handle items like this needs using the correct kind of equipment for the job.

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

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

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