| A safety system for engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the system is implemented as a wiring harness disposed exclusively on the engine which simultaneously disables one or more ignition coils and prevents a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the system further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety. | ||||||

| Carburetors for attaching to fuel-burning engines are described. The carburetors generate improved engine efficiency and reduced engine emissions by improving combustion of fuel. The carburetors include a plurality of nebulizers, each of which nebulizes a thin film of fuel covering a vibrating plate. The vibrating plate vibrates at a high frequency, and this vibration ejects a fog or mist of fuel particles into an air/fuel mixture channel that passes above the nebulizers in series. Air is drawn into the air/fuel mixture channel, passes over each of the plurality of nebulizers in turn, and then passes to a nebulized fuel outlet within a Venturi narrowing of a main channel of the carburetors. The Venturi narrowing provides a reduced air pressure area that performs the function of drawing the air through the air/fuel mixture channel over the nebulizers, thus drawing out the mixed air and nebulized fuel. | ||||||

| A carburetor arrangement for a two-stroke engine (1) is for a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like and has an intake channel (22). The intake channel (22) is partitioned by a partition wall (11) into an air channel (8) and a mixture channel (21). A fuel opening (27, 28) for supplying fuel to the two-stroke engine (1) opens into the mixture channel (21). The carburetor arrangement has a carburetor (17) having a carburetor housing (18) wherein an intake channel section (32) is formed. A throttle flap (24) is pivotally journalled in the carburetor housing (18). A good partitioning of the air channel (8) from the mixture channel (21) results with a simple manufacture of the carburetor (17) when a partition wall section (31, 48, 58, 68, 78, 88, 98) is configured as a separate component upstream of the throttle flap (24) and is held in the intake channel (22). | ||||||

| A fuel metering system for a combustion engine carburetor utilizes a non-convoluted, planar, flexible diaphragm which does not require a molding process to form a traditional convolution. The diaphragm defines in part a pressure controlled fuel metering chamber on one side and a reference chamber at atmospheric pressure on the other side. During operation of the engine, sub-atmospheric pressure within a fuel and air mixing passage draws fuel from the metering chamber to mix with air for combustion within the engine. As pressure within the metering chamber thus decreases, the diaphragm flexes into metering chamber. The displacement of the diaphragm actuates a flow control valve of the metering system which flows pressurized make-up fuel into the metering chamber until the diaphragm returns to its datum position. Preferably, hardware of the flow control valve which is in direct contact with a surface of the diaphragm exposed to the metering chamber does not penetrate the diaphragm as the traditional rivet and washer assembly would. Therefore, manufacturing costs are reduced and any opportunity of leakage between the fuel metering chamber and reference chamber is eliminated. Preferably, the carburetor is of a manual external purge type in order to exert sufficient vacuum within the metering chamber to displace the metering diaphragm thus opening the flow control valve to purge the carburetor of unwanted fuel vapor and air prior to starting the engine. The novel planar diaphragm thereby resolves problems associated with traditional metering diaphragms such as variation in convolution datum height affecting flow control valve lever/diaphragm clearances, non-symmetric convolution axis or distorted convolution affecting diaphragm pressure response and recovery. | ||||||

| A carburetor is supported on a casing by the air-fuel mixture discharging port thereof and by the portion of the adjustment screws thereof. A first vibration isolating member is interposed between the casing and the air-fuel mixture discharging port, and a second vibration isolating member is interposed between the casing and the adjustment screws. These vibration preventing members prevent the direction transmission of the vibration of the casing to the carburetor side. A reasonable and compact carburetor support structure can be provided because the air-fuel mixture discharging port and the adjustment screws are intrinsically provided with the carburetor itself. | ||||||

| A modular diaphragm carburetor is provided which has a plurality of plates each with generally planar faces adapted to be mated and releasably connected together to facilitate manufacturing and assembling the carburetor and to permit various plates and components of the carburetor to be used in carburetors designed for use with different engine families. By providing a plurality of mated together plates, the machining of the passages through the carburetor is made dramatically easier when compared to the machining of a carburetor having a single body with end caps. Still further, the modular diaphragm design permits different plates and/or components of the carburetor to be used with other components to provide a carburetor having different performance characteristics and suitable for use with a different engine family. Therefore, a wide range of carburetors can be provided which have many of the same components to reduce the overall part count and to more economically manufacture and assemble a wide range of carburetors. | ||||||

| Interchangeable venturi sleeves are removably positioned in open-ended bores of a carburetor center section. Each of the sleeves is colored a particular color corresponding to the physical parameters of the sleeve, for example, inner diameter and shape. Similarly, base plates and metering blocks of different capacities are provided such that the operating parameters of the carburetor can be changed. Like the venturi sleeves, the base plates and metering blocks are color-coded to indicate their physical parameters. With this color-coding, the observer can quickly and easily determine the physical characteristics of the carburetor. | ||||||

| An insulator supports a plurality of charge formers on the end of an intake manifold. The insulator, made in part of elastic material, thermally decouples the charge formers from the engine to reduce conduction of engine heat to the charge formers. Expansion of the intake manifold due to heat deforms the insulator, without substantially moving the charge formers so as not to deform a linkage which interconnects the charge formers. | ||||||
