Waste heat recovery (WHR): Did you know about 50% of the energy produced by a diesel engine is wasted? Exhaust heat makes up about half of that. WHR systems look to capture that lost exhaust energy and re-use it, so you get more out of the fuel you burn.
Variable valve actuation (VVA): Already in use in automotive applications, VVA allows an engine to operate in a higher efficiency range. Applying similar technology to construction equipment could mean a 2-3% fuel efficiency gain.
Closed loop combustion control: Another technology already proven in the automotive industry, closed loop combustion allows monitoring and control of the combustion process in real time. By optimizing efficiency across different operating conditions and environments, it could lead to 2-4% improvement in fuel efficiency.
Intelligent foot pedals: Some manufacturers are looking into controls that provide physical feedback to the operator — like foot pedals that vibrate when they accelerate too hard or provide resistance when they need to back off the speed. The goal is to help break the bad habits that can increase fuel consumption.
Cameras vs. mirrors: In Japan, it’s now legal for car manufacturers to replace side mirrors with cameras, as a way to improve safety by eliminating blind spots. But it’s also estimated to improve fuel efficiency by as much as 5%. Could the same hold true for construction equipment?
