Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines which could operate on a mixture of diesel fuel and gas fuel or it can operate on diesel fuel alone. Duel Fuel engines can not operate on gas alone as they do not posses an ignition system, nor do they possess any spark plugs.
As 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 may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which can prove really challenging for lift trucks. Like for example, scrap metal is one of these issues. In order to successfully handle items like this requires 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 liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to several of these particular classes. The main power sources for forklifts include Diesel, Gasoline, Battery, 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. Amongst internal combustion trucks, around more than 90 percent are propane powered.
The battery is the forklifts most popular power source. Battery powered models make up roughly 60 percent of the new forklifts sold in the United States. Their benefits include: less maintenance requirements, quiet operation, the ability to be used indoors and outside with no harmful emissions.
