Dual Fuel Engine
The Dual Fuel engine is a kind of engine which 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.
Because 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 can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved a challenge for the forklift. For instance, scrap metal is one of these problems. In order to successfully handle items like this requires using the right type of machinery for the task.
There are 7 major lift truck classes, including power sources like hydrogen fuel cell, liquid propane gas, 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 IV and V. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, around over 90% are propane powered.
The battery is the forklifts most common power source. Battery fueled units make up about 60% of the new forklifts sold within the United States. Their benefits include: quiet operation, less maintenance requirements, the ability to be used outdoors and inside with no harmful emissions.
