Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could work on a mixture of diesel fuel and gas fuel or it could work on diesel fuel alone. Duel Fuel engines can not operate on gas alone since they do not have 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 equipment does suffer from poor fuel efficiency and Methane slippage. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It can even be lower or higher loads.
Lift Truck Fuel Sources and Classifications
There are some recycling materials handling applications that can prove very challenging for lift trucks. For example, scrap metal is amongst these problems. In order to successfully handle items like this requires using the correct type of machine for the job.
There are 7 major lift truck classes, including power sources such as 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, Fuel Cell and Propane.
Electric powered trucks are the most common, mainly Class III, III and class I forklifts. Internal combustion engines are more common in Classes IV and V. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, around over 90% are powered by propane.
The battery is the forklifts most popular power source. Battery powered units make up approximately 60 percent of the new forklifts sold within the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used inside and outside with no harmful emissions.
