Fuel Pressure Regulator play a crucial role in controlling fuel pressure to the engine to ensure that a vehicle’s fuel injectors are receiving and dispensing fuel at their proper rates. This is to prevent engine flooding or starvation and ultimately maintain efficient engine performance.  Key Functions To ensure there’s proper engine performance for Automotive Fuel…

In commercial vehicles, off-highway equipment, and industrial machines, seamless communication between electronic control units (ECUs) is essential. The J1939 protocol, built on the Controller Area Network (CAN) standard, provides the structure for this critical data exchange—powering everything from engine diagnostics to safety systems. As electrical architectures grow more complex, OEMs often need to connect additional…

In today’s advanced automotive and industrial systems, electronic control units (ECUs) must communicate seamlessly to keep operations running smoothly. Two of the most widely used communication protocols enabling this are CAN (Controller Area Network) and LIN (Local Interconnect Network). While both play key roles, they serve very different functions.  At SMP Engineered Solutions, we help…

Controller Area Network (CAN) refers to a high-integrity serial communications protocol that facilitates interactions between electronic controls, sensors, and electromechanical devices in a system. The network standard accommodates the need for real-time control and secure transmission. While it was originally designed for use in vehicles, its ruggedness and dependability have led to its increasing employment…

Contactors and relays are both solenoid switches that operate in electrical circuits to help ensure the efficiency of the system. They have similar functions and constructions, which results in many people confusing the two and even using the terms interchangeably. At a basic level, the two components function to turn electrical circuits on and off…

The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee developed the J1939 higher-layer protocols to improve heavy-duty vehicle communication. The described standards provide advanced networking technology management capabilities that support messages of unlimited lengths using node IDs. The SAE standards define communication for trucks, agricultural equipment, buses, and other vehicle networks…

DC contactors provide a cost-effective and reliable method to switch current in low-voltage DC circuits. Industries that use our DC contactors include (but are not limited to) agriculture & construction, lawn & garden, marine, mobile hydraulics, heavy trucks, and electric vehicles. DC contactors must be carefully selected with consideration to the expected environmental factors, current…

Digital switching systems are network-controlled hardware devices that replace DC mechanical switches with digital power distribution switching systems. Unlike mechanical switches, digital switching systems are programmable and completely customizable to meet the needs of each application. SMP Engineered Solutions delivers standard and customized membrane switches and keypads for challenging digital switching applications involving harsh environments….
