Methods and systems are described for optimizing engine restarts. In one aspect, the system includes an engine, a brake pedal sensor, and a controller. The controller is configured to shut off the engine when a vehicle stops during an Idle Stop and Go (ISG) operation. The controller operates the engine to shut off during the ISG operation in response to detecting the vehicle being stopped. The controller detects a driving condition indicating that the engine is required to be on. The controller operates the engine to turn on based on the driving condition. The controller detects force satisfying a second threshold at the brake pedal based on the brake pedal sensor. The controller operates the engine to maintain an engine-off state in response to detecting force satisfying the second threshold at the brake pedal based on the brake pedal sensor.

Apparatus and method for optimizing engine restarts

Methods and systems are described for vehicle coasting optimization. The system may include a vehicle having an engine, a drivetrain, and an accelerator. The system may include selecting a fuel-saving mode based on an anticipated braking requirement in response to detecting the vehicle is non-stationary and the accelerator is disengaged. The system may include generating an instruction corresponding the selected fuel-saving mode, wherein the instruction is configured to control at least the engine and the drivetrain.

Vehicle coasting optimization

Methods and systems are described for engine idle speed optimization. A system may include determining whether a fuel intake rate indicative of an amount of fuel consumed by an idling engine over time satisfies a threshold in comparison to a reference fuel intake rate. The reference fuel intake rate may be indicative of a predetermined amount of fuel consumed by the idling engine over time. The system may adjust a predetermined minimum speed at which the engine idles in response to determining that the fuel intake rate satisfies the threshold.

Engine idle speed optimization

A system for a vehicle includes a water separator and a particulate filter. The vehicle includes an engine that emits exhaust, and the water separator and the particulate filter are disposed downstream of the engine and receives at least a portion of the exhaust. The water separator separates water from the exhaust, and the particulate filter filters particulates of the exhaust such that the water may be subsequently used, e.g., for potable uses, operation of the engine, etc.

System for removing water and particulates from engine exhaust

An exhaust after-treatment system including an exhaust passage, a lean-NOx trap (LNT) provided in the exhaust passage, a tank carrying an aqueous reagent, an electrochemical cell in communication with the tank and configured to receive the aqueous reagent therefrom, the electrochemical cell configured to convert the aqueous reagent into a hydrogen exhaust treatment fluid for purging the LNT, and a controller in communication with the electrochemical cell, wherein the controller is configured to vary an amount of the hydrogen exhaust treatment fluid produced by the electrochemical cell.

Exhaust after-treatment system including electrolysis generated H2 and NH3

A system may include an engine, an exhaust passage, a carbon dioxide capture system, and a dosing valve. The engine includes a combustion chamber. The exhaust passage receives exhaust gas from the engine. The carbon dioxide capture system receives exhaust gas from the exhaust passage and may include a separation device, a pump and a first tank. The separation device removes carbon dioxide from the exhaust gas. The pump pumps the removed carbon dioxide to the first tank. A second tank may receive and store carbon dioxide from the first tank. The dosing valve may be in fluid communication with and disposed downstream of the second tank. The dosing valve may regulate a flow of carbon dioxide from the second tank to the engine.
