Dual Fuel Engine
The Dual Fuel engine is a kind of engine that 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 running on gas alone. These engines do not have ignition systems and do not use 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 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 could even be lower or higher loads.

Lift Truck Fuel Sources and Classifications
There are some recycling materials handling applications that could prove extremely challenging for lift trucks. Like for instance, scrap metal is amongst these problems. In order to successfully handle things like this needs using the right kind of equipment for the job.

In this write-up, the 7 major lift truck classes are discussed, including the power sources like 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 include Gasoline, Battery, Diesel, Propane and Fuel Cell.

The most popular 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 common electric power source is the lead-acid battery. Among internal combustion trucks, roughly over 90 percent are propane powered.

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