Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines that could operate on a mixture of diesel fuel and gas fuel or it could run on diesel fuel alone. Duel Fuel engines can not operate on gas alone because they do not have an ignition system, nor do they have any spark plugs.
Since the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from poor fuel efficiency and Methane slippage. For example, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It can 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 one of these problems. In order to successfully handle items like this needs using the correct type of machinery for the job.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, gasoline, diesel and electric. The power source is linked to some of these particular classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
The most common overall are electric powered trucks, mostly in Class III, II and class I forklifts. In Classes V and IV, internal combustion trucks are more popular. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, about more than 90% are propane powered.
The battery is the forklifts most popular power source. Battery fueled units make up roughly 60% of the new forklifts sold within the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used indoors and outdoors with no harmful emissions.
