A diagnostic apparatus for electric vehicle charging is provided. In some aspects, the diagnostic apparatus includes an input connector unit comprising a plurality of inputs that receive electrical signals from a charging station for electric vehicle charging, and an output connector unit comprising a plurality of outputs that send electrical signals to an electric vehicle. The diagnostic apparatus also includes a circuit network electrically connecting corresponding inputs of the plurality of inputs to outputs of the plurality of outputs, and a housing at least partially enclosing the circuit network. The diagnostic apparatus further includes at least one circuit access that exposes at least a portion of the circuit network.

A method of refilling coolant from a fluid cooling system of an engine, where the fluid cooling system has a surge tank or pressure cap, includes the steps of sealingly connecting a storage tank of a coolant management tool to a drainage port of the cooling system, wherein the drainage port is located at the bottom of the fluid cooling system. The storage tank stores the coolant to refill the cooling system. The method includes installing a vacuum module to the surge tank or pressure cap. The method also includes the steps maintaining a vacuum while drawing at least a portion of the coolant from the storage tank up through the drainage port, up through the cooling system, and to a level just upstream of the vacuum module.

A piston insertion force gauge tool for measuring the insertion force of a piston into a bore of a brake caliper includes a housing assembly having an inner housing member at least partially disposed in an outer housing member, where the housing members are generally coaxial and selectively displaceable along the axis. First and second end members form the ends of the gauge tool. The inner housing member is received into the outer housing member at a second open end. A measuring device extends from the second end member through a first open end and to the first end member. The measuring device displaces the inner housing member with respect to the outer housing member to indicate the insertion force imparted on the piston.

A torque limiting engine rotation tool for rotating a crankshaft of an engine, where the engine rotation tool is configured to be operated with a socket wrench or non-impacting tool and is configured to engage an accessory drive pulley bolt or any other bolt that causes the crankshaft to rotate, includes a socket body. The socket body has a driving portion coupled to a bolt-torquing portion with a shear pin. A receiving recess is defined by the driving portion and is configured to receive the socket wrench or non-impacting tool. A female socket recess is defined by the bolt-torquing portion and is configured to engage the bolt. The amount of torque applied by the socket wrench or non-impacting tool to the bolt is limited by the shear strength of the shear pin.

A torque-limiting cap () for an air conditioning service port () includes an inner body assembly () having a retaining body () configured for engagement on the service port, and an outer body assembly () annularly disposed around the inner body assembly. The outer body assembly () has a first ratchet portion () configured for engagement with a second ratchet portion () that is disposed on the inner body assembly (). When the outer body assembly () is torqued, the outer body assembly transmits the torque to the inner body assembly () from the first ratchet portion () to the second ratchet portion () to threadably engage the retaining body () onto the service port (). When there is a preset amount of torque resistance, the first ratchet portion () slips with respect to the second ratchet portion () such that no additional torque is transmitted to the inner body assembly () from the outer body assembly ().

A diesel particulate filter of a motor vehicle is cleaned of ash, typically using equipment already available in a service shop. The method of the invention cleans ash particles from the diesel particulate filter by generating a pressure wave and transmitting the pressure wave into a housing containing the diesel particulate filter. The pressure wave dislodges ash particulates from the filter, which can then be removed from the filter using an ash collecting apparatus, such as a shop vacuum. The method also uses an inflatable bladder in the filter apparatus to close access between the housing and the engine or outside environment.

A method for testing a circuit of a D.C. electrical system in a motor vehicle that includes connecting a load bank () to a D.C. electrical source such as a battery bank () or an alternator () and wirelessly operating the load bank () to set the load that the load bank imposes on the D.C. source during circuit testing.

A cone () and a ring () are accessories separately used during respective phases of cleaning a diesel particulate filter (') in a cleaning machine that uses compressed air pulses to clean the substrate () where particulate matter in engine exhaust has been trapped. In one phase the ring covers the outer perimeter margin of one end face of the substrate, and in the other phase the cone covers a central inner zone of the end face.

The aftertreatment apparatus and method of the invention concentrate diesel exhaust under low engine load conditions in a motor vehicle, such as idling, before filtering the diesel exhaust. The apparatus has a housing which is in fluid communication with a filter and other components of the diesel exhaust system. The apparatus has an exhaust concentrator to concentrate the low load diesel exhaust. The concentrated exhaust is directed a limited part of the filter and/or the catalytic device, such as the center. The exhaust concentrator is at least partially disposed within the housing.

Multiple storage tanks and multiple valves that open simultaneously allow gas charges stored at superatmospheric pressure in the tanks to simultaneously discharge and form a single substantial percussion pulse that dislodges particulate matter from a diesel particulate filter.
