SmartEfficiency: High-Achieve and Cost-Lowering


The Cummins SmartEfficiency initiative is a focused approach that improves uptime and reliability while providing a broad spectrum of reliable engine choices to meet every need. The combination of a low cost of operation, high reliability, clean operation and long-term durability are unsurpassed in the industry. The fact that all Cummins engines use the same control system technology and can be serviced at any authorized Cummins location ensures serviceability anywhere, anytime


Cummins V5.0 goes beyond the traditional diesel attributes of horsepower, torque, reliability and durability to deliver the next dimension of performance. Cummins global diesel design expertise has combined advanced materials, the latest High Pressure Common Rail (HPCR) fuel system, Cummins VGT Turbocharger and Cummins emission control technology to produce an extraordinarily clean, quiet and fuel-efficient V8 diesel engine.

Better Fuel Economy. Big Savings.
Switching from a gasoline V8 to the Cummins V5.0 V8 diesel significantly reduces your cost of operation, as diesel fuel economy is typically 20-40% better than a V8 engine of comparable performance. The V5.0 combines the latest in Cummins combustion technology, with advanced weight-saving components that include a compacted graphite iron (CGI) block, and high-strength aluminum alloy head and composite valve covers. The high power-to-weight ratio of the V5.0 helps you get the most out of every gallon of fuel. 

Proven Technology With A Clear Advantage
The V5.0 utilizes Cummins advanced technology that has been proven effective and reliable in the toughest on-highway applications. This includes a HPCR fuel system, dual overhead camshafts and the Cummins VGT™ Turbocharger. The Aftertreatment System from Cummins Emission Solutions is fully integrated with the engine to deliver optimum fuel economy and near-zero emissions.

VGT™ Turbocharger from Cummins Turbo Technologies – The VGT Turbocharger’s patented design is widely recognized as the industry leader for performance. Precision boost control across the speed range delivers performance and fuel economy.

High Pressure Common Rail (HPCR) Fuel System
 – Higher injection pressures with Piezo fuel injectors produce precise fuel control for optimized in cylinder combustion delivering quick throttle response, quieter operation, better cold-weather starting and better fuel economy.

Cummins Aftertreatment System from Cummins Emission Solutions – Proprietary system features  a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology for better fuel economy with near-zero emissions.

Compacted Graphite Iron Block – Advanced materials technology provides a combination of high strength at reduced weight for a higher power-to-weight ratio, exceptional performance and fuel economy.

Dual Overhead Camshafts – Dual Overhead camshafts deliver high speed capability that improves engine performance. This design enables cost-effective hydraulic adjustment with no maintenance required.

Forged Steel Crankshaft – The crankshaft is created from high-strength, durable micro-alloy forged steel, precision ground for increased durability with smooth, quiet operation.

Advanced Glow Plugs – The advanced ceramic glow plug system significantly reduces startup time in cold weather conditions and the low current draw reduces vehicle charging system requirements. Unlike traditional bi-metal style glow plugs, these ceramic glow plugs are designed to last the life of the engine.
