Fuel-saving devices are sold on the aftermarket with claims they may improve the fuel economy, the exhaust emissions, or optimize ignition, air flow, or fuel flow of automobiles in some way. An early example of such a device sold with difficult-to-justify claims is the 200 mpg ‑US (1.2 L/100 km) carburetor designed by Canadian inventor ...
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
MIL-HDBK-512 handbook is a guide for Military Acquisition Activities (AA) in the preparation of Requests for Proposals (RFPs) with respect to a parts management program, and will help determine to what extent parts management should be for a given program. It will also identify those elements in a proposal to manage the selection and use of parts.
The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally occurring lubricity agents in diesel fuel.
Many drivers have the potential to improve their fuel efficiency significantly. [13] Simple things such as keeping tires properly inflated, having a vehicle well-maintained and avoiding idling can dramatically improve fuel efficiency. [14] Careful use of acceleration and deceleration and especially limiting use of high speeds helps efficiency.
Variable Cylinder Management (VCM) is Honda's term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving. The second version of VCM (VCM-2) took this a step further, allowing the engine to go from 6 cylinders, down ...
Materials management is a core supply chain function and includes supply chain planning and supply chain execution capabilities. Specifically, materials management is the capability firms use to plan total material requirements. The material requirements are communicated to procurement and other functions for sourcing.
Arvin Meritor, a Tier 1 supplier of automotive technology, at one time, was experimenting with a plasma reformer technology which would use hydrogen produced from the fuel to enhance engine combustion efficiency and reduce emissions of NO x. [26] This reference states that a 20% to 30% increase in engine thermal efficiency is possible. However ...
