Simulasi Perancangan Press Tool Cylinder Head Gasket (3X –E 1181–00) Sepeda Motor Yamaha F1ZR

Press tool is a press tool used to cut or form a thin plate into the desired shape with a pressing or press machine. This press tool is designed to be able to produce goods in bulk with a relatively short processing time without reducing the quality of the product, so that work efficiency can be improved and can reduce production costs. The design of the press tool for making cylinder head gaskets (3XA - E 1181 - 00) is a Yamaha F1ZR motor with a thickness of 0.5 mm made from ST37 through two processes, namely the embossing process, besides forming, the punch embossing also functions as a stripper. stock), followed by the cutting tool (piercing and blanking) process. Judging from the type of construction, this press tool belongs to the type of compound tool. In the process of making construction products this type has two workmanship functions but in one step work. The force that occurs is the sum of the cutting force (F _p = Us. R_m). The punch center calculation is useful for knowing the center of emphasis. This component is a gas leak retaining plate on the engine cylinder located between the cylinder block and cylinder head.

Experimental Investigation on Establishing the HCCI Process Fueled by N-Heptane in a Direct Injection Diesel Engine at Different Compression Ratios

Establishing the homogeneous charge compression ignition (HCCI) process in a diesel engine, in order to improve exhaust emission quality while extending the HCCI regime, is one of the challenges in applying HCCI in worldwide applications. This can be done by decreasing the compression ratio, and controlling the exhaust gas recirculation (EGR) rate and charging temperature. In this paper, an original single cylinder diesel engine was converted to n-heptane-fueled HCCI with the fuel injected into the intake manifold. At the designed compression ratio of 20:1, the HCCI engine could operate stably at low speed (from 1600 rpm to 2000 rpm) and low load (10% to 20% load). In addition, reducing the compression ratio from 20:1 to 14.87:1 by changing the thickness of the cylinder head gasket and with no EGR applied extended the operating range to 50% load and 3200 rpm speed.
