Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines which could operate on a mixture of gas fuel or diesel fuel or it could operate on diesel fuel alone. Duel Fuel engines could not operate on gas alone because they do not posses an ignition system, nor do they possess any spark plugs.
Because 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. For instance, 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 greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which could prove very challenging for lift trucks. Like for instance, scrap metal is amongst these problems. In order to successfully handle items like this requires utilizing the right type of machine for the task.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, electric, gasoline and diesel. The power source is linked to some of these specific classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Propane and Fuel Cell.
Electric powered trucks are the most popular, mainly Class I, II and class III forklifts. Internal combustion engines are more popular in Classes V and IV. The most popular electric power source is the lead-acid battery. Out of internal combustion trucks, around over 90 percent are powered by propane.
The battery is the forklifts most common power source. Battery fueled models make up around 60% of the new forklifts sold within the United States. Their benefits include: less maintenance requirements, quiet operation, the ability to be utilized indoors and outdoors with no harmful emissions.
