A remote start system and method for a work machine wherein the system comprises a communication device, an engine starter subsystem, a fluid pressure sensor, and a controller. In a first step, controller receives a wake signal from the communication device, The controller then confirms the lock status of a safety lock on the work machine and outputs an engine start signal to the engine starter subsystem upon confirming the lock status. The controller then receives a fluid pressure signal from the fluid pressure sensor, and outputs an engine stop signal if the fluid pressure signal is below a predetermined threshold after a specified timeframe.

Methods, apparatus and systems for reducing engine idling of fuel-driven equipment, for example found on a wellsite and/or including hydraulic pumping systems are provided. In particular, systems and methods are provided for controlling the starting and shutdown of equipment powered by a fuel-driven engine, the system comprising of an energy accumulator comprising or consisting of one or more supercapacitors. The transmission, transmission fluid, or other components can be warmed to prolong time between engine restarts.

A controller for a vehicle that includes an internal combustion includes processing circuitry. The processing circuitry obtains a predicted temperature outside the vehicle and estimates the viscosity of a lubricating oil based on the oil pressure and the oil temperature of the lubricating oil when the internal combustion engine satisfies a specific operation condition. When the processing circuitry determines that there is a likelihood of a cranking failure occurring in the internal combustion engine on condition that the predicted temperature is less than a threshold value that is based on the viscosity, the processing circuitry outputs a notification signal indicating that that there is a likelihood of a cranking failure occurring in the internal combustion engine.

Methods and systems are provided for adjusting engine cranking. In one example, a method for an engine cold start may include extending engine cranking at least based on one or more engine cold start conditions, where extending engine cranking may increase an engine oil pressure in a plurality of camshaft phaser cavities of a variable camshaft timing (VCT) phaser. In some examples, the method may further include, after engine cranking, enabling fueling. In this way, fuel efficiency considerations may be balanced with increases to the engine oil pressure such that components of the VCT phaser may be actuated and/or lubricated.

Systems for efficiently starting an engine of a hybrid electric vehicle are provided. An example of a system comprises a first processor and a second processor. The second processor is configured to determine when to start an internal combustion engine, cause energy to be supplied from an energy storage device to a generator/motor to cause the generator/motor and crankshaft to rotate to at least a hold speed, transmit a first instruction to a first processor when determining that the internal combination engine should be started. The first processor does not supply fuel to at least one cylinder of the internal combustion engine in response to the first instruction. The second processor is configured to transmit a second instruction to the first processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed.
