A non-pressurized fluid reservoir for a vehicle coolant system includes a bottle configured to store fluid. The bottle has a neck defining an inner circumferential surface that is devoid of threads. The reservoir further includes a cap having a lid and a shank extending from the lid. The shank has an outer circumferential surface and with a spiral ramp supported on the outer circumferential surface to encircle a portion of the shank. The shank is receivable within the neck with the spiral ramp adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.

Non-pressurized coolant reservoir and cap

Various systems for controlling coolant flow through a plurality of coolant lines via a wax thermostat are provided. In one embodiment, a thermostat comprises at least one wax motor that mediates coolant flow between two inlet passages and three outlet passages as a function of longitudinal position, the longitudinal position varying in response to changes in coolant temperature.

Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations. An ultrasonic sensor positioned in a recess at the bottom of the vertical standpipe transmits signals intermittently, receives their echoes upon reflection from the coolant surface, and estimates the fluid level in the standpipe based on echo times.

Method and system for engine cooling system control

Methods and systems are provided for adjusting a compressor recirculation valve in response to condensate forming conditions in a charge air cooler (CAC). In one example, a compressor recirculation valve may be opened in response to an induction pressure greater than a threshold pressure when the induction pressure is greater than required to produce a manifold pressure required for a torque demand. Further, a wastegate may be opened to further reduce the induction pressure during certain driving conditions.

A method for selectively adjusting an amount of fuel to an engine in a vehicle is provided. The vehicle includes an electric machine operatively connected to the engine and capable of controlling a speed of the engine. The method includes providing an amount of fuel to the engine based at least in part on a desired output of the engine, which is based at least in part on a driver input. The electric machine is commanded to control the engine speed based at least in part on the driver input. An output error of the engine is determined based at least in part on the command to the electric machine. The amount of fuel provided to the engine is adjusted when at least one predetermined condition is met, including the output error of the engine being greater than a predetermined amount.
