Abstract: An exhaust gas recirculation system for gasoline engine includes a first exhaust gas return tube, a high-pressure by-pass tube, a second exhaust gas return tube and an EGR control unit. The first exhaust gas return tube includes a hot end, a cold end, a high-pressure EGR cooler, and a high-pressure EGR valve. The high-pressure by-pass tube connected with the first exhaust gas return tube in parallel has a high-pressure EGR by-pass valve. The second exhaust gas return tube has a hot end, a cold end, a low-pressure EGR cooler, a low-pressure EGR valve and a low-pressure EGR pump. The EGR control unit is electrically connected with the high-pressure EGR valve, the high-pressure EGR by-pass valve, the low-pressure EGR valve and the low-pressure EGR pump respectively. Different EGR recirculation manners can be chosen under different loads and different running conditions of the gasoline engine to meet different demands under different conditions.

Abstract: The present invention discloses a bumper-cart light assembly of a golf cart. The bumper-cart light assembly includes a bumper body, a lower support, an integral cart light assembly and two upper supports. The two upper supports are symmetrically arranged at the upper end of the bumper body respectively. The lower support is arranged at the lower end of the bumper. The periphery of the bumper body extends rearwards to form a recess. The upper end of the bumper body forms a connecting tab. The upper end of the bumper protrudes upwards to form a protrusion provided with a receiving groove. The two upper supports are located at the two sides of the protrusion respectively. The middle of the bumper body is provided with an air inlet. The lower end of the bumper body is provided with an upward recess. The bumper-cart light assembly can carry a driving light assembly.

Abstract: The present invention discloses a golf cart windshield including an upper panel having a bend, a lower panel having a bend, and a connecting bar. The connecting bar includes two grooves in which the bends of the upper and lower panels can be clamped respectively.
