In the Philippines, the primary raw material used in biodiesel is Coconut Methyl Ester (CME) derived from coconut oil.
Many journals report decreasing engine torque with the increase in biodiesel content, due to the lower calorific values of biodiesel.

Random manufacturing unit of Petri network and its analysis Assuming a random manufacturing unit is composed of a machine, and: a) the unit will not be material, and will not block; b) a workpiece each only processing, processing time is independent, the machine to perform machining operations after loading the next workpiece; c) machine failures occur only in the machine in the processing, machine failure immediate repair;d) repair after the workpiece for machining the unfinished (another strategy is to give up the workpiece fault occurs and a new workpiece with engineering); e) processing time, machine failure rate and the repair time obeys the random distribution.

Analysis on dynamic characteristics of high speed cylindrical roller bearing Wang Yanshuang a, Jin Ningningb, Zhu Haifengc School of Mechatronics Engineering, Henan University of Science and Technology, Luoyang, China ayswang@mail.haust.edu.cn, bjnn1985@163.com Key words: cylindrical roller bearing; dynamic characteristics; minimum oil-film thickness; high speed; load distribution Abstract: A nonlinear dynamics analysis mathematical model for the high-speed cylindrical roller bearing was built up.
(4) Because of the centrifugal force, the normal force between rollers at no-load zone and the inner ring raceway is, the normal force of outer ring raceway is equal to the centrifugal force .The driving force of rollers from the cage at no-load is: (9) Balance Eq.1 and balance Eq.2 are solved by the Newton-Raphson method .The unknows , can be got. 3 Calculation process Fig.1 Flow chart of dynamic characteristic analysis of high speed cylindrical roller bearing The flow chart was showed in Fig.1.First, geometric Parameters , material property parameters, lubrication characteristic parameters and working condition parameters were input.

Examine the situation of the worm’s alignment and adjust the location of the worm, the dimesion torlarence of the journal is ensured.
Because the worm wheel’s material is wear resistant, the hob’s wear must be prevented, the worm wheel’s tooth profile must be guaranteed as far as possible.

As shown in Fig.2, the force which acting on the generating line of half section can be stated as [3] (4) Thus, the curtailment action () can be expressed as (5) Substituting equation (3) and (5) into (2), and solving for limiting bearing capacity which yields (6) Fig.2 Curtailment action of superstratum to external load From equation (6), the conclusion can be achieved that the factors which are related to launching site bearing capacity are mainly include: structure layer material parameters (,,), clay foundation bearing capacity coefficient which is related to internal friction angle (), the thickness of superstratum (), and the radius of rear davits ().
