摘要： Provided is a step-shaped drill bit including at least two stepped cutting edges that are axially provided. A cutting edge of a first step from a tip is formed so as to satisfy at least one of the following conditions. That is, a number of blades is smaller, a point angle of the cutting edge is larger, or a clearance angle of the cutting edge is larger than that of cutting edges of a second and subsequent step(s). As a result, a thrust resistance during a perforation can be reduced compared with a case in which the first step cutting edge is formed such that the number of blades, the point angle of the cutting edge and the clearance angle of the cutting edge are the same as those of the second and subsequent step(s).

摘要： A drill includes a pair of main cutting edges extending from a distal portion of the drill to a position close to a proximal end of the drill to entirely define a two-edge configuration, and a pair of auxiliary cutting edges extending between positions at the distal and proximal sides of a maximum diameter position to partly define a four-edge configuration. A ridgeline of each auxiliary cutting edge is located within an angle smaller than 90° from a ridgeline of the corresponding main cutting edge toward the rear in a rotation direction of the drill. The point angle of the auxiliary cutting edges increases at a higher rate than the point angle of the main cutting edges in a predetermined range from the maximum diameter position toward a distal end of the drill.

摘要： An EGR control apparatus for an internal combustion engine, which is capable of accurately controlling an inert gas amount and an inert gas ratio of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state and reduced exhaust emissions. The EGR control apparatus includes a low-pressure EGR device, a high-pressure EGR device, and an ECU. The ECU calculates a target low-pressure opening, calculates an estimated value of an in-cylinder low-pressure inert gas flow rate, which is the estimated value of an inert gas amount included in low-pressure EGR gas supplied to the cylinders via an intake passage, calculates a target high-pressure opening using the estimated value, and controls low-pressure and high-pressure EGR control valves, using the target low-pressure opening and the target high-pressure opening.

摘要： An exhaust purification system for an internal combustion engine is provided that can maintain the NOx purification rate of a selective reduction catalyst at near the maximum thereof. The exhaust purification system is provided with an oxidation catalyst and CSF provided in the exhaust plumbing of the engine, a selective reduction catalyst that is provided in the exhaust plumbing on the downstream side of oxidation catalyst and CSF, and selectively reduces NOx in the exhaust, and a NO2 sensor that detects NO2 in the exhaust inside of the exhaust plumbing on the downstream side of the selective reduction catalyst. An ECU executes NO2-NOx ratio decrease processing to cause the NO2-NOx ratio corresponding to the ratio of NO2 to NOx in the exhaust flowing into the selective reduction catalyst to decrease, in a case of a detection value Vno2 from the NO2 sensor being greater than a predetermined value Vno2_th.

摘要： An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability. The EGR control apparatus includes low-pressure and high-pressure EGR devices, and an ECU. The ECU controls the low-pressure and high-pressure EGR gas amounts according to engine speed and demanded torque, and when a combination of engine speed and demanded torque is in a predetermined region, the low-pressure and high-pressure EGR gas amounts are controlled such that inert gas in low-pressure EGR gas exceeds in amount inert gas in high-pressure EGR gas, and the former more exceeds the latter as engine speed is higher or demanded torque is larger.

摘要： A catalyst degradation determination device is provided that can determine the degradation of a selective reduction catalyst with high precision while also suppressing a temporary decline in purification performance. By way of controlling a urea injection device, the catalyst degradation determination device increases, in a selective reduction catalyst in a state in which the storage amount is a maximum, the storage amount thereof by a detection reduced-amount portion DSTNH3—JD and then decreases the amount until it is determined that ammonia slip has occurred. Then, degradation is determined based on the time at which the slip determination flag FNH3—SLIP was set to “1” when fluctuating the storage amount. The detection reduced-amount portion DSTNH3—JD is set to a value that is larger than the storage capacity of the selective reduction catalyst in a degraded state and smaller than the storage capacity of the selective reduction catalyst in a normal state.
