УСТРОЙСТВО УПРАВЛЕНИЯ ЗАЩИТОЙ ДЛЯ МАШИНЫ ДЛЯ РЫТЬЯ ЯМ ПОД СТОЛБЫ, КОТОРАЯ РАБОТАЕТ НА БЕНЗИНЕ

Номер: RU0000174141U1
Автор: ЛЮ Хунвэнь

В данном патенте общего назначения раскрывается устройство управления защитой для машины для рытья ям под столбы, которая работает на бензине. Устройство включает в себя стойку эксплуатации и соответствующие рукоятки, расположенные с двух противоположных сторон стойки: рукоятка управления дросселем, расположенная с правой стороны, и рукоятка управления равновесием, расположенная с левой стороны. Устройство управления защитой монтируют сверху стойки ближе к левой стороне и соединяют при помощи одного дроссельного кабеля с двигателем посередине стойки эксплуатации и при помощи второго дроссельного кабеля с рукояткой управления дросселем с правой стороны. Длинный сенсорный стержень устанавливают под устройством управления защитой с возможностью выхода наружу из стойки эксплуатации в положение А, как показано на фигуре внизу. При использовании машины для рытья ям под столбы буровое долото вгоняют в почву по часовой стрелке. Если буровое долото задевает крупные корни или камни и внезапно прекращает вращение, то вся сила инерции и крутящего момента, которые вырабатываются все еще работающим двигателем, будет приложена к стойке эксплуатации, что приведет к ее повороту в противоположном направлении против часовой стрелки. Затем сенсорный стержень, который, как правило, выходит из рамы в положении А, поворачивается, чтобы коснуться ноги и вращается под определенным углом по отношению к позиции В. Обнаружив это изменение угла, устройство управления защитой активируется и уменьшает крутящий момент двигателя, освобождая дроссельный кабель, чтобы замедлить скорость. В результате, чтобы избежать опасности падения оператора, машина всегда должна находиться в комфортных условиях управления. Устройство, описанное в настоящем патенте, безопасно в эксплуатации, имеет простую конструкцию и чрезвычайно практично в использовании.

An amount of inlet air can be delivered to a combustion volume of an internal combustion engine via an air inlet port, and delivery of an amount of a fuel from a compressed fuel reservoir to the combustion volume can be controlled via a pressurized fuel inlet port positioned to the deliver the amount of the fuel directly into the combustion volume separately from the air inlet port. The amount of the fuel can be controlled relative to the amount of the inlet air to create an air-fuel mixture within the combustion volume having a target air/fuel ratio. In other aspects, a vehicle chassis can be designed to incorporate a compressed fuel reservoir as a structural part of the chassis. Methods, system, and articles of manufacture relating to these features are described.

A method and a system for starting an internal combustion engine (ICE) having a crankshaft and an electric turning machine (ETM) operatively connected to the crankshaft are disclosed. An absolute angular position of the crankshaft related to a top dead center position of a piston in a combustion chamber of the ICE is determined. Electric power is delivered to the ETM at a first level to rotate the crankshaft. Electric power is then delivered to the ETM at a second level greater than the first level when the piston reaches a predetermined position before the TDC position. Fuel is injected in the combustion chamber after the piston has passed beyond the TDC position. The fuel is then ignited. In an implementation, the ICE is started in less than 110 degrees of rotation of the crankshaft.

Start control device for saddled vehicle

Номер: US20180086205A1
Принадлежит: Honda Motor Co Ltd

When start control is initiated, the start control device operates in a first operating mode in which an upper limit value of an engine speed is limited to a first upper limit value (NErev 1 ) that is lower than an upper limit value (NErev 0 ) in a non-start control. When an elapsed period of time after a throttle opening has exceeded a predetermined opening in the first operating mode reaches a predetermined standby time, the start control device operates in a second operating mode in which the upper limit value of the engine speed is limited to a second upper limit value (NErev 2 ) that is lower than the first upper limit value. The start control device transitions to an ordinary mode to thereby terminate the start control when a period of time of the second operating mode reaches a predetermined control period of time or a forced cancellation condition holds.
